Twin Air Air Filter - Yamaha YZ / WR

Twin Air dual-stage foam air filters for Yamaha YZ two-strokes, YZ-F, YZ-FX, WR-F and WR250R/X models from 1997 to 2026, plus the Fantic models built on Yamaha engines. Pick your bike from the Fitment dropdown and Dry or Pre-Oiled from the Version dropdown, or click a part number below to select it. Each filter replaces the stock one, and you can wash, re-oil and reuse it.

• Outer foam: coarse open-pore foam catches dirt, grime and sand
• Inner foam: fine open-pore foam traps the smallest particles and keeps air flowing
• Sealing ring: thick, flat, greaseless foam that seals to the airbox
• Adhesive: holds up to repeated cleaning, even with harsh solvents
• Dry or pre-oiled: the Dry version comes unoiled, so oil it before you ride. The Pre-Oiled version is ready to install, with Twin Air oil already applied (not offered for the WR250R/X filter).

Clean it with Twin Air Bio Dirt Remover or Maxima Air Filter Cleaner, then oil it with Twin Air Liquid Power or Maxima FAB-1. The Maxima Air Filter Care Kit has a can of each.

From 2015 (WR250F) and 2016 (WR450F) on, the WR-F uses the same filter as the YZ-F: 152218, then 152221. Earlier 2003–2014 WR-Fs use 152215. Twin Air doesn't list the 2023+ YZ450F or 2024+ YZ250F here, so call us for those.

Other Twin Air filter listings: KTM / Husqvarna / GasGas (incl. 2023+ Fantic XX/XE), Honda CRF, Honda XR, Kawasaki KX, Kawasaki KLX / KLR, Suzuki and Beta.
