WASHABLE AND REUSABLE: designed to last the lifetime of your vehicle.

REUSABLE K&N FILTERS SAVE YOU MONEY: A K&N washable, reusable air filter will save you up to £125 vs. purchasing multiple disposable filters (compared to MSRP in GBP of corresponding OE filters for 200,000 miles of highway driving)
