Description
No-Toil Standard Air Filter – Yamaha WR250F/WR450F & YZ250F/YZ250FX/YZ450F/YZ450FX – 180-52
Protect your Yamaha’s engine from damaging dirt, dust and debris with the No-Toil 180-52 Standard Air Filter. Designed for select Yamaha YZ and WR four-stroke motorcycles, this washable and reusable foam filter provides dependable engine protection while maintaining the airflow needed for responsive power.
The filter features dual-stage foam with two different pore sizes. The coarse outer layer captures larger dirt, sand and debris, while the finer inner layer helps trap smaller dust particles before they can enter the intake system.
Unlike filters that rely on adhesive between the filtration layers, No-Toil flame-laminates the two foam stages together. This heat-sealed construction helps provide maximum airflow without creating a restrictive glue barrier between the layers.
Reticulated open-cell foam increases the available dirt-trapping surface area while improving the strength of the filter. Flexible seams resist cracking during installation and servicing, while OEM-style dimensions provide the sealing surface and dirt-holding capacity required for demanding motocross, trail and cross-country riding.
