Ok first things first.
1.Go to lowes buy a 3in diameter pipe. Then guesstimate to the far corner of your stock air box cut off excess. Then attach the air filter at one end and the put everything together. Your air tube should fit right into your stock air tube. Then measure where you want your CAI air filter to sit. Get everything good to go and hook it up.
