Chevrolet Silverado 3500 Intercooler Pipe - Driver Side - Wehrli - 3" High Flow - Illusion Blueberry - 17-19. This WCFab 3-inch hot-side pipe replaces the factory two-piece 2.5-inch tube on 2017-2019 L5P 6.6L Duramax trucks for higher-flow, sturdier charge plumbing.

Built as a one-piece upgrade, it helps reduce restriction and improves durability under high boost and heat. The kit includes multi-layer silicone boots and stainless T-bolt clamps to curb boot failures, plus a durable Illusion Blueberry powder coat. It installs as a direct bolt-on with no tuning or other modifications required. Replaces GM 87839947 and fits Chevrolet Silverado or GMC Sierra 2500/3500 HD with the L5P.
