yeah i had the same problem, it came no where near close to fitting, i just took a pair of dikes and cut about 3/4" out off that blue rubber ring around the fenderwell peice, , i was able to spread it out more then becareful too with the metal nipple for that little crankcase e-vac line that goes back into tthe valvecover, i had to getr it just right for it to stay in the CAI w/o popping off. and i dont care what anyone says it did make a difference of my cobra. and i just installed my UPR o/r X pipe bolted to my stock "sport tuned" mufflers, and it sounds awsome now
