Air Filter Cleaning  

Maintenance > K&N FilterCharger Cleaning

 
  • Maintenance: Cleaned K&N Performance Air Filter

  • Odometer: 81128 km (50413 miles)

  • Cost: Approximately $18 CAD for Cleaning Kit

  • Time required: 20 min of work plus 24+ hours of waiting

  • Note: Unless you want to drive around without an air filter, you won't be able to use the car for this time.


The recommended interval for cleaning the permanent K & N FilterCharger is 50,000 to 100,000 miles. I decided to do it a little on the early side. 

Procedure

  • Removing the air filter is straightforward and is basically the same procedure as installing it. You have to remove the cover, the mid-section of the air flow pipe, release four clips, and unhook a couple of tubes to get enough clearance to get the filter out.

 

  • These are the steps for cleaning the filter

  • This is the filter after cleaning.
  • After rinsing with tap water I gave the filter a shake, set it flat on some newspaper, and it seemed pretty dry. But when I took it down to the garage and held it vertically, a bunch of water came out. Sooo...I thought it best to let it sit on its side for 24 hours just to make sure it was completely dry.

  • This is the filter with new oil applied.
  • I've heard of some people having problems with their MAF sensors, possibly because of over-oiled filters, so once again, I let it sit vertically for 24 hours to allow any excess oil to come out.
