§ 02 / About this part

What it is

Twin Air Powerflow-kit replacement backfire air filter to fit Honda CRF250R (2004–2005); Honda CRF250X (2004–2014); Honda CRF450R (2003–2008); Honda CRF450X (2005–2014).

This replacement foam is specifically designed for use with high-flow intake kits that remove the stock backfire screen. It features a laminated layer of flame-resistant foam to prevent engine backfires from igniting the filter. This element sits on your aftermarket cage to provide maximum protection for the top-end without restricting airflow. Replace the foam when it shows signs of degradation or after multiple washes. Ensure the filter is fully oiled and seated correctly against the intake flange. It is a vital component for maintaining engine safety and performance on modified bikes.

§ 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.
