Team went above and beyond to locate the part needed to get my can back on the road asap.
I finally got to install the intake which literally took 10 minutes. The power and launch difference was insane! You can hear the turbos spooling a lot better as well. I’m amazed by the difference just from the intake
Great product and communication.
I went with the super low, extended rear shocks , Swift 9/7k upgrade and absolutely love the stance and how the truck rides. It’s tight in the corners , smooth driving down the hwy and not bouncy at all. Thanks to Brian for getting me set up.
Everything seems in good condition and good quality, appreciate the help from brian for all my questions and to setup the shipping to canada
