    Default Thoughts on K&N Air Filters.

    I have been reading some opinions over at Bob is the Oil Guy and apparently there are a LOT of folks that belive K&N air filters are the worst thing you can put on your vehicle.

    The speak of large amounts of engine damaging dust being sucked into the engine, ruined MAF sensors, accelerated engine wear, etc.

    Apparently the only evidence to support this claim was a test done back in 2004 by Arlen Spicer.

    I've used K&N air filters for years with no problems.

    My thing is, if K&N air filters were so terrible, would not competing air filter makers test their air filters against K&N, publish tests to try to get people to buy their filters over K&N?

    This has been bought up many times.. And as you said many People have used K&N filters in everything from Motorcycles to $100K race motors with never a problem.. K&N has done it's home work to bring you a trouble free filter and has done the testing to prove it more then any other Co out there... I have used them now in my past 4 trucks with over 100K on all before I got Sold them.. NEVER a problem other then running out of recharge oil..

    I think the problem is people don't recharge the filter right. Then they blame the filter not their error.

    I am going to change the oil soon and will send off some used oil to Blackstone Labs for a UOA.

    If the K&N is not doing its job, I should see elevated levels of silicon in the results.
