§ 02 / About this part

What it is

The K & N AIR FILTER REPLACEMENT SUZUKI DRZ400 00-09, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This high-flow filter replaces your restrictive foam element inside the airbox. It cross-references with OEM part 1378044E00 for a precise fit. The pleated cotton media increases surface area for better airflow without sacrificing filtration. It sits securely in the factory housing to prevent dust bypass. Unlike disposable filters, this unit is washable and reusable. Clean and re-oil it as part of your regular service interval. It provides a reliable seal for trail riding or road use in dusty conditions.

§ 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.
