Description
Description
Stage 1 upgrade for the 2017-2019 L5P Duramax improves airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool up. Eliminates weak points in the factory design that can lead to boost leaks or complete failures in hard working and high performance applications.
Kit replaces the restricted 2-piece, resonator equipped, 2.5 in. diameter driver (Hot) side intercooler pipe and leak-prone 2-piece plastic / rubber passenger (Cold) side pipe with WCFab's heavy duty 3 in. diameter 1-piece Driver (Hot) Side and 3.5 in. diameter Passenger (Cold) Side L5P Intercooler Pipes. Made in the USA from high strength, heavy duty 14 ga. aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow.
3 in. Driver Side pipe eliminates the OEM resonator and middle boot joint for improved flow and durability and includes high quality reinforced silicone boots and stainless t-bolt clamps for superior temperature resistance and boost pressure holding capabilities.
3.5" Passenger Side pipe features a CNC machined flange with a double o-ring seal and an upgraded silicone boot in order to withstand higher boost pressures than the factory components to increase reliability and eliminate blown factory boots and horsepower robbing boost leaks.
Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.
Installs with basic hand tools. Compatible with stock trucks, no tuning required. Saves $25 vs. buying individually.
