K&N 77 Series Metal Intake Kit Reviews

K&N 77

Reviewed By Ramiro L (NEW CANEY, TX) Reviewed for a 2012 GMC Sierra —3/29/2016 8:44 PM

Everything I was expecting and more. Installation was a breeze, the only thing I was missing is the three screws for the top cover. But overall it looks great and sounds even better when you need that extra power.

Volant HV Cold Air Intake Replacement Filters with Donaldson PowerCore® Filtration Technology Reviews


Reviewed By Peter B (Owego, NY) Reviewed for a 2012 GMC Sierra —3/2/2016 4:14 AM

I've been running the Volant CAI system in my 2012 GMC Sierra 5.3 since about 20,ooo miles and just replaced it @ 125,000 miles. I haven't noticed much change in power or gas mileage. But, my truck runs great, doesn't use a drop of oil between changes and I am confident that it is breathing clean air. And for that piece of mind it's worth the investment. note that I only use synthetic oil and change regularly by the truck's system indicator (clock).

S&B Cold Air Intake Kit Reviews

better egts

Reviewed By David W (FISHERS, IN) Reviewed for a 2012 GMC Sierra —12/31/2015 4:16 PM

After only a few days and on my first empty road trip egts are down about 100 degrees but the ambient has also dropped. After running hard for 3 hrs cool down to 350 from 625 was much quicker but again it is only 30 degrees out. Once back into summer and rv season I will be able to better compare before and after.
