K and N Air Filter
 

Hey,

I know the pros, but what are the cons. Can it allow to much air flow that will cause particles to get in and cause problems?

Thanks

There's no such thing as too much air. The air flow is limited by the displacement of the engine.The mosta filter can possibly do is to be a very small part of the total pressure drop thru the entire intake system.

Separate from this, people have said K&N allows more dirt thru, which can be measured as silicates in your oil. That is, if you have oil analysis done before and after installing the K&N. I haven't done that so I can't say firsthand...

Another thing is more Hondas these days are equipped with a hot-wire air flow sensor in the airfilter housing. You need to be careful to NOT over-oil a K&N filter so you don't get oil deposition on that sensor.
