Wehrli 20-24 Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - Gloss Black

This 3-inch diameter driver side intercooler pipe from Wehrli Custom Fabrication is built to replace the restrictive, two-piece factory pipe on your 2020-2025 6.6L L5P Duramax Silverado or Sierra. The factory pipe is often a bottleneck for airflow, and this single-piece, larger diameter unit helps improve how efficiently your engine breathes, especially under load.

Wehrli didn't just increase the pipe size; they also included upgraded silicone boots and T-bolt clamps. These components are designed to handle higher boost pressures and temperatures than the stock parts, which helps prevent leaks and blown boots that can sideline your truck. The gloss black powder coating not only looks sharp under the hood but also adds a layer of durability. This is a bolt-on upgrade that doesn't require any tuning, making it a straightforward way to enhance your truck's intercooler system.
