Air Cleaners

Air Cleaners: the intake face that feeds your engine clean air

An air cleaner is the housing and filter that sits at the mouth of your intake, straining dirt and grit out of the air before it reaches the throttle and cylinders. On V-twin motorcycles it's also the most visible piece of the engine, which is why so many air cleaners pair a functional filter element with a machined or carbon cover. Swap one in to replace a tired stock unit, open up the intake path, or change the look of the motor. It's a straightforward bolt-on job on most bikes, but the fit has to match your engine and mounting.

What ThreePiece stocks

There are 99 air cleaners in this category right now, spanning 15 brands. The current price range runs from $25 to $1,238 for what's in stock - that's the live spread, not a fixed price. The deepest range comes from S&S Cycle with 44 listings, followed by K&N Engineering at 16, Edelbrock at 7, and six each from Performance Machine and Vance and Hines. You'll also find Kuryakyn, HKS, Bikers Choice, Ford Racing, Skunk2 Racing, Vibrant, BLOX Racing, Radium Engineering, SLP and Spectre.

Concrete examples: the S&S Cycle Stealth Air Cleaner Kit for 2017+ M8 models with a carbon fiber cover, the Vance & Hines VO2 Rogue and its black finish counterpart for Touring and Softail, plus Performance Machine's C4 Series in carbon fiber for 17-23 Touring and 18-24 Softail and 23-up CVO and 2024 Touring. At the top of the range sits the HKS S Type O/C Kit for the BNR34.

How to choose

Fitment data covers 48 of these products, and the coverage leans heavily to Harley-Davidson - Big Twin, Softail, Touring, M8, Sportster, CVO, Tri Glide, Road Glide and Street Glide all appear, with Rover and Ford also turning up in the data. Match the air cleaner to your exact engine family and year first; an M8 kit won't fit a Twin Cam, and a car intake kit is a different animal entirely.

After that it's a trade-off between complete kits and simpler covers. Full kits like the S&S Stealth include the filter, backing plate and cover in one part number, which is the cleaner install. Cover-focused pieces such as the Performance Machine C4 Series lean toward finish and appearance. Carbon fiber and Black Ops covers cost more; that's what pushes the top of the range past $700. If you only need the filter itself, a housing swap may be overkill.

What else you need

If a full air cleaner is more than you want, look at Replacement Air Filters, Drop In Filters, Panel Filters or Air Filter Elements. For car intake builds, browse Cold Air Intake Kits and the wider Air Intakes section.
