**UPDATED 5/19/21**
Up for sale is the parts I had for my 2015 GT A6 Premium that I kept before I traded it in on my brand new Charger Hellcat.
All parts have 5000-6000 miles on them
Used 1320 Junkie ported 2018+ intake manifold w/Lethal PnP IRMC harness for 15-17 GT
Used 2018+ PMAS tune...
I’m going to upgrade my 2015 gt intake manifold to 2018 intake manifold ported but I’m wondering does that require me to change the gaskets? Knowing that my milage is 70k+ km
