§ 02 / About this part

What it is

Twin Air Powerflow-kit replacement backfire air filter to fit Yamaha WR250F (2001–2002); Yamaha WR400F (1998); Yamaha WR426F (2001–2002); Yamaha YZ 450 F SP (2006); Yamaha YZ250F (2001–2013); Yamaha YZ450F (2003–2009).

This replacement foam is designed specifically for use with a Powerflow cage. It features a laminated layer of flame-resistant foam to protect your bike from backfire damage. This allows you to remove the restrictive metal backfire screen from the intake tract. It sits deep in the airbox and requires a proper oiling routine to maintain its filtration properties. Replace this filter if the foam shows signs of thinning or the base seal loses its shape. It is essential for maintaining airflow while protecting the intake from combustion spikes.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. Brands you'd find on a paddock workbench — pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere; dirt and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
