You have seen a dyno chart of a G/Z that gained power from a drop in k&n filter?

 

Well I was just asking because i Have K&N filters on my CAI that's all thanks guys.

 

From the OP's post, he has a intake(s), not drop-in replacements.

That said, Greg just made a blanket statement re: K&N filters causing trouble without clarification as to drop-in, CAI of various manufacturers, etc.

 

If K&N made an in-cabin air filter, would you use it? If the extra dirt is good for you engine, surely it's good for your lungs too.

I was referring to the drop-in variety..... in an old Q45 a drop-in K&N can reduce power in hot weather.

Also, the "C" in CAI is misleading since a cone-type filter often pulls air from under the hood -- which is a lot hotter than outside air. Don't assume intake mods are always beneficial.
