Trying to get a OEM cold air intake for my 2021 5.3L Sierra 1500. They can't pull anything up by my VIN yet - got the truck in April and it does not have the engine cylinder shutoff chip, which I am ok with. Wish I could find a dealer that knows if the 2020 cold air intake is identical to 2021. The 2019 and the 2020 are different part numbers even though I think they are the same engines. So scared to buy it as it is a special order $ up front, even when they install it and do the required change in tune.
