BMW Performance Air Intake

[SapphireBlack]

Hi All,The mileage on my E90 325i is coming to 30k km soon and it is on BMW Performance Air Intake since day 1. Is it time for me to change the air filter or just wash & oil kit using K&N Maintenance kit?If I were to replace it... appreciate some good recommendation where I could get a replacement air filter to drop in... :rock:Thanks..

Just wash it using the K&N kit, leave it to dry and re-oil it. I have used one on my older cars for 150,000km
