i own a 2018 e-assist silverado 5.3L. dont have an honest opinion yet of the hybrid feature but love the truck. i have a cat back exhaust with a flowmaster super 10, throttle body spacer and an air/oil seperator. what i want to add is a cold air intake but have been unable to to find one due to truck being an e-assist (mild hybrid). tried a K&N cold air intake but due to the radiator resovoir being in the way, the mandrel will not fit. On the GM PARTS online site, they have a performance intake (Performance Air Intake Upgrade, 5.3L
Part Number: 84794977) that says it will fit my Gas/Electric truck. I went to order and later that day i recieved an email from a salesperson who stated that part may not fit and i should do research before buying. i cannot find anything online that says there is a cold air intake that will fit my truck. Has any E-Assist owners come across an air intake that fits or have installed the GM Part 84794977 sucessfully? Thanks
Has anyone used this PSI Power Tuner or found where others have used this? I found the product on two different sites; the 2nd URL has better details on the product. I'm skeptical on this product, being that no other tuners have released products for the 3.0L Duramax (LM2).

Also, what about these two products?

What do you guys think? It's not as loud as a full aftermarket exhaust would be but I think it sounds pretty good for the money I paid.
