I have an AFE OEM style cold air intake that fits the 5.3 and 6.2 of the 2015 (and similar) Chevy 1500 (and I believe some of the suburbans and tahoes, etc). It was on the truck about a year. These are $450 new.
$275 OBO plus freight (if I can get a box large enough to ship it, this one may be tough) or local pickup in central Ohio.
