Best Air Filter For Harley Davidson: Compare 10 Options

#1 · Best Overall

1. K&N HD-0800

• Dimensions: 6.5"L x 6.4"W x 3.6"H
• Dimensions: 6.5"L x 6.4"W x 3.6"H

Best for: 29442-99 series cross-checkers.

Why it ranks #1: The HD-0800 part number, washable pre-oiled cotton gauze, and stated dimensions make this a well-specified reusable element for matching assemblies.

K&N’s HD-0800 is identified with the 29442-99E replacement number, providing a concrete cross-reference for owners comparing a Harley filter to an existing part. Its pre-oiled, washable cotton-gauze construction also gives this high-flow option a reusable maintenance route.

The HD-0800 model and 29442-99E part reference give buyers a direct way to compare the filter with a replacement listing. K&N describes treated cotton-gauze layers that trap dirt and contaminants, while high airflow is intended to support horsepower, acceleration, and engine response. Because the filter is washable and reusable, owners can service the element over time. The supplied details do not include a full model-year application chart, so matching the motorcycle remains a necessary buying step.

Skip it if you need fitment spelled out by motorcycle model and year; LOCOPOW HD-0800 lists multiple Harley families and some year-specific applications.

This suits owners using the 29442-99E reference to identify a washable, reusable HD-0800 replacement. Its high-flow and filtration claims are relevant, but the supplied fitment details do not establish every compatible Harley model year.

#2 · Broad HD-0800 Fitment

2. LOCOPOW HD-0800

Best for: 29442-99E replacement shoppers.

Why it ranks #2: Lists replacement numbers 29442-99A through 29442-99E and numerous Dyna, Touring, and Softail applications; buyers must verify the exact bike.

Support for the 29442-99A through -99E replacement numbers makes the LOCOPOW HD-0800 a useful option when matching an existing Harley filter reference. Its listed applications span Dyna, Touring, and Softail families, helping owners identify a replacement across several model lines without relying on a universal-fit claim.

The multiple 29442-99-series references, including 29442-99E, give buyers several ways to cross-check the filter against an existing part listing. LOCOPOW names Harley families including Dyna, Road King, Road Glide, Electra Glide, and Softail, with years shown for a number of applications. That breadth can simplify the initial shortlist, but it does not replace checking the exact motorcycle: the supplied fitment text is incomplete and the product gives no washable or reusable maintenance details.

Skip it if you need confirmed coverage for a specific year not shown in the supplied list; consider K&N HD-0800, whose listing identifies the same replacement number.

This suits Harley owners cross-referencing a 29442-99-series filter and seeking a replacement for a listed Dyna, Touring, or Softail application. Treat the model-year list as a starting point, since the supplied fitment text does not show every application.

#3 · Compact Dimensions

3. SOLLON HD-0800

• Dimensions: 6.25"L x 6.25"W x 2.36"H
• Dimensions: 6.25"L x 6.25"W x 2.36"H

Best for: Washable HD-0800 replacements.

Why it ranks #3: Gives HD-0800 replacement references and dimensions of 6.25 by 6.25 by 2.36 inches, with washable and reusable construction.

Washability and reusability distinguish the SOLLON HD-0800 from a disposable-style replacement, giving owners a clean-and-reuse maintenance option. It lists Harley replacement references 29442-99A through -99D and KN HD-0800, alongside applications including Road King, Electra Glide, Dyna, and Softail models.

The stated cross-references let owners compare the SOLLON filter with an existing 29442-99-series or HD-0800 listing before purchase. SOLLON also describes high airflow, exceptional filtration, and a design intended to boost horsepower and acceleration, connecting the element to both airflow and filtration goals. Its washable, reusable construction supports repeat service, while the supplied dimensions—6.25 by 6.25 by 2.36 inches—offer a further reference when comparing the listed replacement element.

Skip it if you need a complete year-by-year application chart before selecting; K&N HD-0800 identifies the same replacement family in a separate listing.

A reasonable match for owners seeking a washable HD-0800-style replacement and willing to cross-check their motorcycle’s application. The supplied dimensions and replacement references help with comparison, but do not amount to a complete model-year fitment chart.

#4 · HD-1614 Option

4. K&N HD-1614

Best for: HD-1614 reusable filter seekers.

Why it ranks #4: The HD-1614 listing specifies a washable, reusable high-flow element for bikes matching that part number; its stated warranty is 1,000,000 miles.

K&N’s HD-1614 reference gives buyers a specific filter identifier, while pre-oiled, washable cotton gauze provides a reusable maintenance option. The listed high-airflow design targets horsepower, acceleration, and engine response, making it a fitment-led choice for riders seeking a serviceable filter element.

Treated cotton-gauze layers are described as trapping dirt and contaminants, connecting the filter’s material to engine protection. K&N also says the high-airflow design can help improve horsepower, acceleration, and response without typically requiring fuel-management modifications. Washing and reusing the pre-oiled element offers a maintenance alternative to routine replacement. However, the supplied listing does not name compatible Harley models or years, so the HD-1614 reference alone is the key information available for application matching.

Skip it if you require named model-year applications before selecting; MINSTAR HD-1614 lists selected Harley families and years for that reference.

Choose this if HD-1614 matches the filter you need and you value washable cotton gauze with airflow-focused claims. Confirming the application is the boundary: the supplied K&N details do not spell out compatible Harley models or years.

#5

5. MINSTAR HD-1614

Best for: 2014–2017 Harley fitment shoppers.

Why it ranks #5: Names replacement numbers 29400045 and HD-1614, lists numerous touring and Softail applications, and includes a one-year warranty description.

The HD-1614 replacement reference is the key identifier for this MINSTAR filter, whose listed applications cover selected Harley models from the 2014–2017 period. It gives owners a part-number route for matching an air filter to named Softail and Touring motorcycles, rather than claiming broad fit across all Harley models.

MINSTAR lists replacement reference 29400045 / KN HD-1614 and names applications including Softail Slim, Softail Classic, Fat Boy, Deluxe, Breakout, and Heritage, as well as selected Touring models. Those identifiers give buyers a practical starting point for narrowing a replacement search by model family and part number. The listing directs users to Amazon’s Part Finder for fit confirmation, and it does not provide washable or reusable maintenance details, so this is best treated as a fitment-led replacement choice.

Skip it if you need a washable, reusable filter with stated cleaning instructions; SOLLON HD-0800 explicitly lists washable and reusable construction.

Consider this for owners whose Harley appears among MINSTAR’s named 2014–2017 applications and whose existing filter matches the HD-1614 reference. Its fitment is application-specific, so the listed model and year remain important boundaries.

#6

6. K&N HD-0910

• Dimensions: 10.3"L x 10.1"W x 3.9"H
• Dimensions: 10.3"L x 10.1"W x 3.9"H

Best for: Screamin Eagle ventilator replacements.

Why it ranks #6: A washable, reusable cotton-gauze element identified as HD-0910; the supplied listing does not give a detailed motorcycle fitment list.

K&N identifies this HD-0910 as a Harley-Davidson Screamin Eagle Ventilator element, giving owners of that intake a specific replacement reference. Its pre-oiled cotton-gauze layers are washable and reusable, while the high-flow design targets improved horsepower, acceleration, and engine response.

The named Ventilator element designation helps distinguish this filter from K&N’s other Harley-numbered options when matching an existing intake. Treated cotton-gauze layers are described as trapping dirt and contaminants, and the high-airflow design aims to support engine response and acceleration. Since the filter is pre-oiled and washable, routine servicing can involve cleaning and reuse rather than automatic replacement. The supplied information does not give a model-year fitment chart, so the intake reference remains the main application clue.

Skip it if you need explicit Harley model-year coverage before buying; MINSTAR HD-1614 lists selected model families and year ranges.

A targeted option for riders matching a Screamin Eagle Ventilator element who want washable cotton gauze and airflow-focused claims. Its application boundary is the intake match: the supplied details do not spell out compatible motorcycle years.

#7 · 114 Engine Fit

7. M Maintenanse 114 Filter

Best for: Milwaukee-Eight 114 owners.

Why it ranks #7: Targets 114-equipped, later-model Softail, Touring, and Trike applications and is washable; the box contains the filter element only.

The 114L element targets Harley Milwaukee-Eight 114 applications, including 2018-and-later Softail and 2017-and-later Touring and Trike models with a 114 air cleaner. Its washable construction and special coating offer a repeat-cleaning path while helping filter fine particles from incoming air.

This is an element-only package, which keeps the choice focused on replacing the filter rather than buying an entire intake kit. The listing describes 360-degree air intake and accordion mesh, linking the design to airflow and filtration, while washable construction supports repeated cleaning. It also notes that the coating’s oil dissipates over time and the filter can turn gray; cleaning the surface and applying Air Filter Care products renews its appearance and coating treatment.

Skip it if you need gaskets and bolts included for an intake installation; TOPRAMETAL’s Drift-style kit lists a complete gasket and bolt kit.

This fits owners of the specified 114-equipped Softail, Touring, or Trike models who need an element-only replacement and accept periodic cleaning and care-product application. It is not the choice for buyers assembling a complete intake kit.

#8

8. MOTOKU Turbine Filter

Best for: Touring intake kit installers.

Why it ranks #8: Lists Touring fitment for 2008–2016, plus specified Dyna and Softail applications, and includes accessories; follow its bolt-tightening caution.

This MOTOKU listing pairs an air-cleaner filter with accessories, making it a kit-style choice for riders replacing more than the filter element alone. Its applications include Harley Touring models from 2008–2016, with additional Dyna, Softail, and Trike fitment details for selected years.

The stated coverage includes Street Glide, Road King, Electra Glide, and Road Glide in the 2008–2016 Touring range, plus specified Dyna, Softail, and Trike applications. That range helps owners narrow whether the kit suits their motorcycle before installation. MOTOKU specifically cautions installers to tighten bolts evenly and avoid excessive force, giving the aluminum bracket’s thread-stripping or fracture risk practical relevance. The listed 8–12 N·m recommendation makes careful, even tightening central to the installation workflow.

Skip it if you want a washable, reusable filter with care details; TOPRAMETAL’s Drift-style kit specifies washable cotton-yarn media that requires oiling.

This is for owners whose listed Touring, Dyna, Softail, or Trike application matches and who are comfortable following the tightening guidance. Pay particular attention to even bolt pressure, because excessive force can damage the aluminum bracket.

#9

9. TOPRAMETAL Drift Cleaner

• Dimensions: 7.15"L x 5.24"W x 7.13"H
• Dimensions: 7.15"L x 5.24"W x 7.13"H

Best for: Complete washable intake kit buyers.

Why it ranks #9: Offers multiple fitment types, a washable cotton filter requiring oil, gasket and bolt kits, and a one-year quality guarantee.

A complete gasket and bolt kit accompanies TOPRAMETAL’s air cleaner, while its cotton-yarn filter is washable, reusable, and requires oiling. That combination suits owners seeking both intake hardware and a serviceable filter element, with fitment options divided by Harley model family and year range.

TOPRAMETAL separates fitment into types covering Sportster, Dyna, Softail, Touring, and Trike applications, so buyers can use the relevant group rather than assume one configuration fits all. The washable, reusable cotton-yarn media can be cleaned and oiled for continued service, while the included gasket and bolts provide parts for the kit installation. Some named model-year exclusions apply within the fitment groups, making careful selection by type essential before assembling the intake.

Skip it if you need a filter element only for a 114 air cleaner; M Maintenanse 114L lists an element-only package for specified 114 models.

This suits Harley owners seeking a fuller intake-kit package and willing to maintain an oiled, washable filter. Match the correct fitment type carefully: the supplied listing gives model-family exclusions, so coverage is not uniform across the stated ranges.

#10

10. K&N HD-1717

• Dimensions: 20.68"L x 13.78"W x 7.35"H
• Dimensions: 20.68"L x 13.78"W x 7.35"H

Best for: Reusable cotton-gauze filter seekers.

Why it ranks #10: The listing describes reusable cotton gauze and high airflow but supplies no Harley fitment list or matching vehicle applications to confirm compatibility.

Pre-oiled, washable cotton gauze gives the K&N HD-1717 a reusable maintenance path while its high-airflow design targets engine response. The maker says airflow can help improve horsepower, acceleration, and response without typically requiring fuel-management modifications, making it relevant to riders looking for those benefits in a powersport filter.

K&N combines layers of treated cotton gauze, which trap dirt and contaminants, with a high-airflow design intended to support horsepower, acceleration, and engine response. Because the filter is pre-oiled and washable, owners can clean and reuse it rather than treating it as a one-time replacement. The supplied details identify it as model HD-1717 but do not provide a Harley fitment list, so buyers need an independent fitment match before choosing it for a particular motorcycle.

Skip it if you want an explicitly listed Harley model and year; K&N HD-0800 supplies replacement-number context for that cross-check.

Choose this for a rider seeking a washable, pre-oiled cotton-gauze filter and airflow-focused performance claims. Its practical boundary is application verification: the supplied information names HD-1717 but not the Harley models or years it fits.
