Wehrli Custom Fab High Flow Intake Bundle Kit for 2020-2025 Chevrolet/GMC (6.6L) Gloss Black - WCF100414-GB
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2020-2025 Chevrolet Silverado and GMC Sierra 2500/3500 HD models (6.6L L5P Duramax).
The Wehrli Custom Fab (WCFab) High Flow Intake Bundle Kit is a comprehensive induction solution designed to eliminate the flow restrictions of the factory L5P setup. This Stage 2 kit replaces the OEM intake and the leak-prone plastic/rubber intercooler pipes with heavy-duty 14-gauge mandrel-bent aluminum components. The 4-inch turbo inlet pipe is paired with an air box enclosure and a dry filter assembly, protected by a hydrophobic Outerwears pre-filter cover to keep your MAF sensor and turbocharger free of contaminants.
Beyond the intake, this bundle upgrades the restricted 2.5-inch driver-side (hot) pipe and the 2-piece passenger-side (cold) pipe with 3-inch and 3.5-inch diameter alternatives. By utilizing CNC-machined flanges with double O-rings and high-quality silicone boots with stainless steel T-bolt clamps, this kit provides a superior seal capable of holding higher boost pressures than the factory clip-ring design. This is a complete bolt-on upgrade that requires no aftermarket tuning.
