Wehrli 20-24 Chevrolet L5P Duramax High Flow Intake Bundle Kit | Chevrolet Silverado (WCF100414-CR)

The Wehrli WCFab Candy Red High Flow Intake Bundle Kit is a Stage 2 intake and intercooler-pipe upgrade for the L5P Duramax. Its 4-inch turbo inlet is reported to deliver a 25-horsepower gain when paired with a Max Effort Tune. The kit includes high-quality hardware, a silicone boot, seals, and stainless-steel T-bolt clamps for durability and easier installation. A removable air-box lid element simplifies filter inspection and maintenance, while the included hydrophobic pre-filter cover helps protect the MAF sensor, turbo, and engine airways from contaminants. The intercooler pipes are made in the USA from heavy-duty 14-gauge aluminum, with smooth mandrel bends designed to support airflow and long-term durability.

Designed for 2020–2024 Chevrolet vehicles equipped with the L5P Duramax engine, this bundle upgrades the intake and post-turbo intercooler piping. The Stage 2 pipes replace the restricted, resonator-equipped 2.5-inch, two-piece driver-side hot pipe and the leak-prone, two-piece plastic-and-rubber passenger-side cold pipe. WCFab’s replacement pipes measure 3 inches on the driver side and 3.5 inches on the passenger side, and use one-piece construction. The kit also includes a WCFab filter and hydrophobic pre-filter cover, along with the specified installation hardware and seals. A Max Effort Tune is noted for the reported horsepower gain; no other tuning or use requirements are specified.
