Has anyone put a cold air intake on a chevy 5.3. if so did it make a dif
I put a K&N 77 series on my old 5.3 Silverado, and it didn't do a damn thing. It did make the truck run hotter with the metal tube, but that was about it for me. My honest opinion is that was the biggest waste of $300 I have ever spent, I am now going to do the real ram air thing with my truck through the hood.
i did a stage 2 cold air AFE intake noticed a big difference and i love it...but i have exhaust to i think that helps alot then just doing a cold air intake
if you want the most outta your CAI, you NEED to get full sized exhaust and headers... that will be part of a complete system.
HOWEVER< CAI works best with other parts, and that is what all the parts manufacturers get their HP and Torque numbers from.
CAI on its own is not really a HUGE upgrade... but it does help in mileage.
I have had three systems on my last few trucks. My a 2000 5.3 had a K&N setup and seemed to give me more seat of the pants power and better mileage. My 2003 GMC 5.3 had a K&N and it seemed to make no diff in power but had better mileage. My 2004 Reg Cab 5.3 had a Vararam and it seemed to have more power but no diff in gas mileage. All of these trucks had aftermarket exhausts, so it is a gamble at best if you ask me.
I first added the different intake before anything to my truck, the only difference I had was in the upper RPMs. the engine revs just a tad quicker when giving it the nuts at highway speed to pass someone. No increase in mileage though. For me having a suburban I got it were it counts out of the intake, trying to build speed with a 5000lbs truck, every little bit helps
I noticed more throttle response and better mileage with my K&N. Just make sure you get a plastic tube and not a metal tube.
