DNA Motoring CAI-950021-RD For 1999 to 2006 GMT800 V8 Truck/SUV 4" Aluminum Air Intake System (Red Filter / Silver Pipe / Black Heat Shield)

2005 Silverado. It's ok I suppose if its just an older vehicle that you're just trying to freshen up a bit. The quality is definitely not great, the support arm is off by 1 inch and short about a 1/2 inch. The hose bracket clip didn't line up but, I made it work out so it does not rest on the upper radiator hose. The shield that goes where the old airbox was, didn't align to the body lines of the truck or the holes at the same time, just one or the other, but my impact made the deciding adjustment for both all to fit. The rubber couplers are about 1/4 in to big, I put a few rounds of tape over the ends of the pipe to secure the fit before sliding the rubber couplers over . I don't recommend installing this on a new or newer vehicle. Spend the extra $100-$200 more for a better made item. For $45 on a vehicle with 200k miles, it will do just fine with some fine tuning. You can definitely hear and feel the difference after it's installed (at least I did) No instructions were included, but I'm sure a novice could get this installed because it's pretty straight forward and while the original was completely off, that was a good time to clean out the inside of the throttle body. The ends of the aluminum tube were sharp also. Hope this helps.
