2017-2019 Duramax Passenger Side Intercooler Pipe Kit (L5P-INT-A042)

The factory passenger side charge pipe on the L5P is plastic, and once you turn up the boost it's known to leak or crack. Ours is 6061-aluminum, TIG welded, and built to handle the pressure a tuned truck puts through it. It connects to the factory intercooler with a quick-disconnect coupler we designed in-house, sealed with two O-rings where GM used one, so it stays locked in and doesn't blow off. There's a properly placed bung for the air intake temp sensor, so your readings stay accurate. 

Part Number: L5P-INT-A042
