K&N - detrimental to car?

[wallbanger]

is there any evidence that the K&N air filter or the oil component is harmful to the engine?

Some sensors don't like getting intimate with that red crap!

Typically the oil-sub filters do not trap particulates down to the level you get when using paper filters.

Here's a cool article testing a number of filters:
Filtration Testing for Amsoil, K&N, Napa, Jackson Racing, Baldwin, and Mazda air filters on a Miata

If you have to have the extra airflow, K&N is good, if you want to maximize engine life, use paper and change often.

The SRT engine developer told me at VOI that the R&D that went into the 08' air box and filter left NOTHING to spare and that a filter change would do nothing but possibly loose power and or cause a code from the possible contamination. I would just leave well enough alone.

What about 03-06 SRT? Will the K&N cause codes there as well?

No we have seen nothing to deter you from using the K&N or the Green filters on the Gen 3 cars.

The filters are fine but the most important thing is to use a very light coating of oil on them.

What about GEN ll. Also I heard that the Race vipers use stock air filters over K and N for the reason of longer engine life. Is this still valid?

Use the Oil where on the filter and whats the purpose ( I know the K and N come oiled)? Maybe to trap very fiune dirt particles.

You only need to re oil if you have cleaned the filters I believe it will swell the fibers and help ti catch small particals. It has be said though that the more dirt up to a point the better the actual filtering gets.
