Wehrli 2020+ Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - Gloss White
Upgrade your 2020+ Chevrolet Silverado HD or GMC Sierra HD with the Wehrli Custom Fabrication Driver Side 3-inch Intercooler Pipe in Gloss White for the 6.6L L5P Duramax diesel engine. Engineered from high-grade mandrel-bent aluminum tubing, this intercooler pipe delivers significantly improved airflow over the restrictive OEM plastic components — unlocking better turbo response, lower charge air temps, and increased power potential from your L5P Duramax.
Wehrli's intercooler pipes are precision-fabricated in the USA and finished in a brilliant Gloss White powder coat that resists heat, oil, and road grime while giving your engine bay a clean, custom look. The 3-inch diameter matches or exceeds OEM inner diameter for optimized airflow, and all connections use quality silicone couplers and T-bolt clamps for a leak-free, long-lasting seal.
