Hey, Is there have to be a filter specific for air filter in our kia's or can i really just be at choice? Ever since my Straight through design exhaust my intake seems to be trying to suck harder for my air. Thinking of possiblities other then that cone like filter. I found a tube looking one that is appx. 4" long and 3" dia. Found it at John deer trackers equipment. Was going to make somthing of it but damn the hot air really does build up under out hoods. and I don't wanna do a snorkel don't wanna cut the frame at this point.
