§ 02 / About this part

What it is

Twin Air Powerflow-kit replacement backfire air filter to fit Honda CRM250 (1993); Honda XR250 (2001–2009); Honda XR250L (1986–2004); Honda XR250R (1985–2004); Honda XR400M (2005–2008); Honda XR400R (1996–2006); Honda XR600R (1985–2000); Honda XR650L (1993–2009, 2012–2021, 2023–2025).

Designed specifically for use with a Powerflow kit, this filter features a laminated layer of flame-resistant foam. It replaces the restrictive OEM backfire screen to increase airflow into the intake. This is essential for tuned engines requiring maximum oxygen intake. The dual-stage design provides superior filtration in harsh enduro or MX conditions. You must oil this filter thoroughly before installation. Check the foam integrity during every service. If you notice any tearing or thinning of the flame-retardant layer, swap it immediately. Proper fitment against the cage is critical.

§ 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.
