K&N Filters What are your thoughts?

[UrS4Eben]

I just bought a replacement flat-panel but I know there has been some words about it.
What are your thoughts on this?

MAF's can be killed by excess oil as i had one go on my old Impreza, it was'nt a K&N i used btw it was a ITG.

I have a K&N panel fitted to my S2, just to be sure all i did is use a paper towel or two and wipe of the excess oil before fitting it.

No probs as yet and its been in there 3k miles so far

Ive got the K&N FILTER no running probs but very loud over stock its in a RS2 Airbox.

Sorry to resurrect an old thread but is a MAF sensor hard to replace or expensive? Just wondering in case I get a replacement K&N filter element and dont manage to clean it off properly.

Yes but don't bother with the K&N just use stock and change every year. IMHO all noise and no performance benefit

People kill the MAF by over oiling the replacement filter, K&N or otherwise. The MAF can be cleaned if you suspect this has happened.

Oil the filter ONE SIDE ONLY (fresh air side)so that it just changes colour and leave it for an hour to fully soak in. Been running the same ITG Pro filter for 5 years (maybe due a change?) with no problems, MAF elements were only slightly dirty when i cleaned them.

As for power increase, hmmmmmm dubious.

The only real advantage is if you feel like cleaning the filter regularly as opposed to replacing it.

They K&N stock replacement filter is better, but also louder, as mentioned here, be careful with the oil on it, if it gets to the maf, the maf burns of the oil, and if it gets to hot then the MAF wolfram thread brakes to the excess heat.
