K-kid, the performance ofcoz are better if compare with stock. Bcoz it can sucking more air (even is hot air).
suck hot air is not a good for the engine performance...if wanna play with open pot CAI and Heatsheil is very important isue,
i prefer open pot,more air go in ya,i like the sound when hight rev 6.5k rpm
1 thing i dont like the hot air suck into my airfilter and go true the injector....it would slow down my performance....so before you i chose open pot make sure you setup a good CAI & heatsheild
just my 2cent,as u can see the airfilter position are face to the radiator,
while your engine heatup the radiator fan spining all the hot air from the
radiator will directly suck into your Air filter,u need a heatsheild and CAI
else drop in would better then this

personal expirance i use:
HKS,APEXi, AND K&N before
untill now i chose K&N reason just easy,washeble,low maintain,
1.HKS,the replace cotton fracking expansive around RM80++ original green,i can't effort every time to change the expansive cotton
2.APEXi,unwasheble,when reach the milliage u need to throw away the air filter and brought a new one..
i try to wash & air gun spray b4.....result the air filter "kong"
