Upgrade the restrictive factory charge air system on your 2020-2026 Chevrolet Silverado HD or GMC Sierra HD equipped with the 6.6L L5P Duramax diesel. The SWAG Performance Parts Performance Intercooler Pipe Kit is engineered to improve airflow, increase boost reliability, and give your engine bay a premium polished appearance.
The factory intercooler piping is designed to meet production costs and emissions requirements, but it can become a restriction as airflow demands increase. Plastic factory components and narrow transitions can contribute to pressure loss and reduced efficiency, especially on tuned trucks or those used for towing. The SWAG Performance Parts Intercooler Pipe Kit replaces these restrictive components with smooth mandrel-bent aluminum tubing that promotes more efficient airflow from the turbocharger to the intake, helping improve throttle response, turbo efficiency, and overall boost consistency.
Each kit is manufactured from high-strength aluminum and features a brilliant polished finish for long-lasting corrosion resistance and an aggressive underhood appearance. Premium multi-ply silicone couplers and heavy-duty stainless steel T-bolt clamps provide a secure, leak-free connection capable of handling higher boost pressures than the factory system.
Whether your truck is completely stock, tuned for additional horsepower, or used for daily towing, this intercooler pipe kit delivers the durability, performance, and appearance serious Duramax owners demand.
