Very nice print. Its the cheap t-shirts that they all use but the print is nice its been washed it hasn't cracked yet so I avoid washing it till I have to and I def do not dry it. I really enjoy it even tho I didn't win the truck

Customer photo review of FSD 03-09 Dodge Cummins Billet Heat Exchanger

I'm totally pleased with my purchase and all the up grades that I've done to accommodate the FSD Heat Exchanger. Everything is working good and if i could i would add another one and also add a coolant bypass.
