For to anyone thinking about this, you'll see an instant difference in intercooler performance and in turbo whistle. Instead of blowing up like a balloon, this solid pipe delivers pressure as soon as the turbo spins up.
To install, be sure to unplug the ECU connectors just above the lower intercooler input to give you room to work without damaging the wiring harnesses. I did my best and took my time and I still ended up with a few battle scars on the pipe, but I didn't do this for looks.
Great product and I plan to buy anything these guys make for the '21 L5P!
