Default K&N Cold Air Intake

I am buying a K&N Cold Air Intake for a 2011 JKU in the next couple days. I am looking for feedback on mileage and performance.

I have the AEM not the K&N but I will say you will get some seat of the pants power increase and the mileage will probably be a wash. You driving style will change because of the throttle response so you might even take a slight loss in mpg's

I won the K&N in a raffle. No change in performance. Just a slight whistle under load.

Go with a drop in K&N, intakes you won't gain much besides noise. Drop in you still open up the air for a third the cost.

Pardon my ignorance, but what's a drop in? Just another term for bolt on?

It is just a K&N filter that fits in the stock air box.

sort of, by the term drop in he means that it bolts up the existing intake, not an actual cold Air intake.

A drop in is just another term for a free flow air filter that fits your stock box hence it drops right in. A bolt on is where you remove and replace the factory intake completely. A strap on is .... oops wrong forum.

Happy with AEM. I'm sure K&N will be a good system also. The cold air intake definitely give you a crisper throttle response. Can be a little loud under full throttle because you can hear it pullin in the air.
