Hello everyone. I recently purchased a 04 Elantra Gt 5 door. Im just curious if you think buying a CAI kit is worth it or not? Id like to keep things as stock as possible on this car but id also like a touch more horse power to it. HOw much do one of these run by the way? Cause if its reasonable then I may purchase one. Also where should I look to buy one of these? Thanks for your help.
