Engine Hesitation on 5.3L 2014 Silverado
I have a 2014 Silverado with a 5.3L. I installed a k&n cold air intake to help with gas mileage when it had about 4k miles on the truck. It started shaking and hesitating between 30-35 mph. I figured, more air in needs more air out. So i added dual exhaust to see if it would help. So far nothing. Now with 38k miles the shaking started getting worse and even at the higher speeds.
1. Does the Cold Air intake void my warranty
2. What could be the issue, only adding these small items?
Thanks

The solution seems obvious....ditch the non-OEM air intake. Not sure where you got the idea that the aftermarket one had some benefit other than for the seller. It certainly would be legitimate for GM to decline any warranty of any part of the engine associated with the quality of the intake air, all the way to the cylinder walls and the cats.
