My JK is due for an air filter change. Anyone drop in a high flow filter like k&n in their JK? I usually use these as my first filter replacement on all my vehicles that i've owned over the past 10 years or so. On the ones with 4 cyl engines, I really have to look for any performance improvement. On my xterra with the 261 hp v-6, I feel a very pronounced improvement on acceleration. I've heard that the more power you start with, the easier it is to detect an increase in throttle response and acceleration.

 

I just installed the Afe Dry Pro filter. Nice design and it SEEMS to give the JK a little more pep. Maybe it's just the little bit of extra sound that it makes??? Either way, I like it!

 

Here's the AFE, would be my choice for a drop in:

I got the same afe dry drop in and noticed no change in sound, but I also noticed a hair more pep. I hate to admit it, but I really did.

 

Might have noticed a tiny bit more pep, but that might just be due to the $50 I spent on it.

 

I have a KNN and like it. I don't know if there is any more pep or not. Its been in there for 45K miles I don't remember what is was like without it.

 

running a kandn also. dont remember if i got any pep. kind of doubt it from an air filter.

did not make it off the dealer lot without my KNN

 

i like the look of the other one looks like you get a little more air then the K&N i wish i would have seen that one before i got the K&N one. i guess i can always get the other it's not to expensive. maybe something i will add this week.
