AT4flex

I just recently found out someone online found part number 84789802 is CARB approved with an EO number from GM directly which includes an ECU flash in part of your part purchase done by the dealer. Still searching for verification and I did ask the online Youtuber who posted the video where I can find it. I've been scouring the net and nothing for the past 6 months. Hopefully he's right.... Repost/reply if someone else in the thread locates or finds it online. I will continue my search. Aside from that.... Its the K&N 57 Series OEM Performance Air Intakes 57-3108
