Wehrli Custom Fabrication 2020-2024 L5P Duramax Stage 2 High Flow Intake Bundle Kit - WCF100414

Stage 2 upgrade for the 2020-2024 L5P Duramax combines our Stage 1 High Flow Bundle and Stage 2 Intake Kit into a single package providing increased airflow for your turbo and engine for improved efficiency, throttle response, and turbo spool up. Eliminates weak points in the factory design that can contribute to lost power, boost leaks, and complete failures in hard-working and high-performance applications.

On the air intake side, our high-flow fabricated intake pipe, intake horn, and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on 2020-2024 L5P Duramax Diesel for improved engine performance and sound. Significantly increases airflow to your turbo producing improved horsepower and torque and cooler intake temperatures by drawing cold air through the hood Ram Air duct and inner fender. All aluminum 14 ga. construction features large diameter 4 in. piping with smooth aerodynamic bends. It improves intake air velocity, and volume, and provides a more aggressive engine and turbo sound during acceleration. The intake horn is over an inch larger than the OEM diameter.

High quality hardware, silicone boot, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation. Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free.

After the turbo, our Stage 2 kit also upgrades the restricted 2-piece 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 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 is 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 $64 vs. buying individually.
