K&N BM 1324 Engine Air Filter: High Performance, Washable, Replacement Filter, Increased Performance

INCREASE HORSE STRENGTH AND BETTER ACCELERATION: K&N 4-layer oiled cotton fabric allows maximum airflow while maintaining maximum filtration. Washable and reusable: designed to last the life of your vehicle. CLEANING EVERYTHING ONLY EVERY 5 YEARS: The engine air filter only needs to be cleaned every 75,000 miles under normal highway conditions (5 years based on the average annually driven 15,000 miles). REUSABLE K&N FILTERS SAVE MONEY: An K&N washable, reusable air filter saves you up to £125 compared to buying multiple disposable filters (compared to the RRP in GBP for corresponding OE filters at 200,000 miles highway driving). Easy, quick installation: fits directly into the OEM air box.
