Review on ACDelco GM A3087C Air Filter: Genuine Original Equipment for Optimal Performance by Ryan Gillett

Helps to fix Code P0101 on Gmc Sierra 2500 Duramax 2008. After trying to fix the P0101 code by replacing the MAF sensor, accelerator pedal assembly, cleaning the EGR valve and of unsuccessfully checking for inlet leaks. I figured I'd try replacing a stock K&N replacement filter (worth 250,000 miles) (which always ran dry with no oil or pre-filter) with this factory replacement filter and it immediately cleared the p0101 code I was getting . I've driven almost 2500 miles since transitioning to hot, cold, dry and wet weather and the check engine light still hasn't come on. 👍👍
