Bull!

I use it on all of my rides and it keeps lots of crap out. Cleaning time is fun. Make sure it is dry first after cleaning.......i know from EXP
 
yeah, noticed a slight increase in engine response.

some people I know that have run K&N's air filters have also noticed the oil from the air filter lining their intake pipes.

Could that be from people over doing the oil when reapplying? If they used the recommended amount they should be fine right?

It still catches some dirt, but it doesn't catch as much as a paper filter.

More flow = less filtration for a given filter area. Always and forever with no exceptions.

K&N does NOT filter as well as a paper filter. Also, it takes over 100,000 miles before it pays off.

Paper Filter: $20.
K&N: $60.
K&N Oil Kit: $20.
Paper filter life: 30,000 miles.
Time to break even on the K&N: 120,000 miles.

Plus there's the hour or two filter cleaning instead of the 5 minute replacement of a paper filter.

this was following the K&N directions. Others let it dry longer. Same results.

It doesn't necessarily mean that more dirt is getting into the intake and engine. If a paper filter is overly restrictive and all significant dirt could be filtered by a more porous material, there's no reason not to use a K&N filter and get more power.

If I start with me sitting in the driver seat with the door and hood closed it will take me 10 seconds for the Sebring linked in my sig.

Yes, I put a K&N in a perfectly good Supra and the head gasket blew 9 months later. No more K&N for me.

I think you had more problems than that K&N filter
 
K&N filters just as well as a paper filter from my experience. That said, we only used K&N filters on our Impala SS and Corvette Grand Sport. In other words, in vehicles with high performance engines.
 
Plenty of independant studies around on the net, they Do let more dirt pass thru the filter.

Does this hurt the motor long term, depends how long you keep the car or truck.
