im trying to make a sheild for my aem cai filter because it's sitting right behind my huge opening in my bumper. this thing gets dirty so fast its not even funny. also, it probably sucks in more dirt that way. i've heard ppl using a 2 liter bottle and cutting it up to make it act like a shield. if anyone knows how to do this or if anyone has tips on what i should do, post up! thx!
