are those the filters that came with the intake? How much is it sticking out? are you sure the pipes are pushed in all the way?

 

These are the filters that came with the kit and yes, the pipes are pushed all the way in and last time I cleaned my airfilters I also tried moving the pipes around to get the filters as high up as I can. They don't stick out an insane amount but I am wondering if those filters I showed would alter performance negatively. Here's a night time shot of the filters sticking out:

 

I'd leave the K&N filters on. Just man-up and clean them a bit more often, its one of the realities of owning an aftermarket intake designed to give you added performance. Flow/design has been fully tested on that system with the K&Ns, and K&Ns are known to be excellent quality filters. (fwiw i have the nearly identical stillen g3 setup)

 

well then there's nothing you can really do. Like diablo said, stick with the those filters and just clean them more often

 

Any cone filter will work. Just match the outer diameter of the tube.

 

I would speculate and say that you wont lose HP because those filters are shorter and probably has a bit more air inlet. But I would stick with the Injen. They were engineered with them.

 

what about making the CAI shorter? just a thought u probably dont wanna cut it. maybe try to use an airbox around it?
