Intake off 2008 gmc Sierra 2500. I believe it will fit 07.5-14 I may be wrong and only fit 07.5-10 should fit Chevy or GM duramax. Does have some carbon build up from EGR. Vehicle has 160k on it, Nothin a couple washes cant fix. Nothin wrong with it took it out for full delete kit. Honestly dont even know what its worth but shoot me an offer.
