Hey all, I'm in the process of making a design for my own custom CAI. I decided for a filter to use a K&N (seems to be the best and most widely used) filter. I can't decide however which would be the best one to use, or will it really make a difference? I've been looking at these filters:

Any suggestions? Thanks.

 

i honestly don't even notice a difference except camera angels lol

 

Theres dimensions are different in the filters. I'm probably looking to hard into this aren't I?

 

Bigger is better.. Spectre makes the same exact problem and are identical more or less.. and are much cheaper than K & N; you're really just paying for the name really.

 

Which ever one is the largest and still fits where you need it to.

 

look at an amsoil filter. you can see through a k&n , and if you can see light, dirt comes right in.

 

Yeah if you look at the studies on the "High Flow Filters" they are around I think the numbers were like 94-96% filtration rate; and once the partials start sticking it increases its filtering ability. Where as a paper filter was around 98-99%

I forget the numbers.. but yeah.. Problem is the fine partials that can make it through can also make it through even with a paper filter; they always tend to find a way.. like on my wife's car. As these things age; youll get some degree of fine dust partials..

 

like they said bigger is better, i know a kid that had a denali k&n in his raptor lol had to cut the air box
