So I have a strange noise that I can not figure out what it is. It is happening at different speeds and just started. The truck is a 2015 GMC Sierra 5.3l z71. If I give it a little more gas or let off the gas the sound goes away. Almost like an exhaust leak sound but do not hear anything at idle so hard to identify. Only thing done to truck is volant power core cold air intake.

  Scanners, much like HP printers, should be sold for much less considering how much they charge to keep them in updates or ink respectively. Can't fault the quality of each but it's hard for some to pay the tolls.

  Lots of info in this thread I was not aware of. How long has Mann-Hummel been in business? It's getting harder and harder to not do business with China. Guess my next stop will be the dealership to pick up a few of the new, "improved" filters for my 5.3. If it's gonna fail I'd rather it be with a GM-approved filter.
