Chevrolet Silverado Intercooler Pipe Kit - Driver Side - Wehrli - 3" High Flow - Grey - 2020–2025. This driver-side hot-side kit replaces the factory two-piece 2.5" tube on the 6.6L L5P Duramax with a single 3" high-flow pipe in WCFab Grey.

Designed for stock trucks, it installs as a direct bolt-on with no tuning required. The one-piece layout reduces potential leak points compared to the OE design, and the larger diameter supports improved charge-air flow under boost. Included upgraded silicone boots handle higher pressure and temperature than stock to increase reliability, and heavy-duty T-bolt clamps deliver consistent clamping force. A durable single-stage powdercoat finish helps resist under-hood heat and grime.
