Cleaning K&N Filters

darklordvader · Nov 10, 2007

The K&N filter on our 2.5 diesel is really dirty, I have no idea how old it is ,my question is can you clean them? I thought I saw it somewhere that you could, but I might be wrong . If you can what can you clean them with , I have done a search on the forum for the answers but there appears to be nothing if anybody has any clues I would be most grateful for their help.

Cheers.

i assume you have a pannel filter rather than a cone type, k&n filters are amade of cotton (rather than paper) and can be cleaned go on K&N High Performance Air Filters, Oil Filters, & Cold Air Intakes - Official K&N Engineering Site and look for cleaning fluid, give it a good wash with that (jizer might work) then give it a coat of the k&n oil as this is what stops the fine particals of dirt

Stick it in the woodburner - thats the best way for a KnN.

Remeber if you are re-oiling the filter that you should probably clean the MAF/AFM (Air Flow Meter) a few weeks afterwards. The oil will stick to the hot wire sensor and could harm performance. They can be cleaned by liberally spraying the MAF with solvent cleaner and leaving it to dry.
Just a thought as the oil is pretty nasty!

Which is why you should stick it in the woodburner and enjoy the warmth from it - the car was designed to run with a paper air filter which works very well.

Nooooooooooooooooooooooooooooooooooooooooooooooooooooo dun't spray it with solvent if its a hotwire it'll kill it! if you must clean it use a pan of boiling de-mineralised water then dry with compressed air solvent cleaner WILL damage it
