Just curious and would like to know what happens if the filter is hella dirty? Would It lower performance or cause the car to have idleing problems? Reason I ask is because I had that idle problem but after I installed my new cai the idle problem stopped and I noticed that my short ram was hella dirty. Just trying to investigate all possible issues that could lead to this dam idle problem since Ive tried almost all the other solutions with no prevail. Also never had the problem when I had my stock intake problem.
