Lordyboi 5 Report post Posted November 16, 2022 Drop in K&N air filter, been in my car for 2 years around 10,000 miles. It was removed and cleaned every oil change so has been cleaned two times. Second time was after i removed it to sell. Still got plenty of life left in it. Removed as I have now installed a cold air intake, so no longer required. It has been re-oiled and sealed in a food bag so is read to drop straight back into the car.Note was cleaned using genuine K&N cleaner and oil. The detergent was washed out from the air flow side only so not to force the dirt into the filter. It was oiled from the air inlet side only to prevent oil transfer onto the MAF sensor.£35 +2.99 shipping Share this post Link to post Share on other sites
