nofxdenk 0 Report post Posted March 10, 2011 (edited) Hi guys, Was just wondering if anyone has any tips on how to clean a K&N air filter? I got my E46 with it already installed into the original air box, but have heard that the cleaning kits that you get for those filters can damage Mass Airflow Sensor? Any suggestions? Thanks.

Apex 693 Report post Posted March 10, 2011 I just clean mine with petrol, I spray it ever so lightly with some sewing machine oil I have. Its the excess oil that clogs the sensor in the AFM. Quote Share this post Link to post Share on other sites

Hi Apex, thanks for that, Do you use a brush or something like that or just drain it in petrol, let it drip off and apply oil? How much oil do you apply? Thanks.

AFAIK it's not the cleaning kits that damage the MAF, it's usually caused by over oiling after cleaning. Edited March 10, 2011 by kinetik Quote Share this post Link to post Share on other sites

Thanks. I just pour petrol into a pan and soak it, all the sh*t sinks to the bottom and the petrol normally turns dark and dirty. You only need a small about of oil, its only there to attract dust. Like you, my car came with a cleanable panel, I wouldn't waist my money on a new one. Quote Share this post Link to post Share on other sites
