Product Description

Wehrli Custom Fabrication Stage 1 High Flow Intake Bundle Kit, Gloss Black. Designed to enhance airflow efficiency, throttle response, and turbo spool-up by replacing restrictive factory intercooler pipe components with high-quality, heavy-duty alternatives. Replaces the driver and passenger side multi-piece 2.5in factory intercooler pipes with WCFab's 3in driver (hot) side and 3.5in passenger (cold) side intercooler pipes, made in the USA from heavy-duty 14-gauge mandrel-bent aluminum for a smooth, aerodynamic, unrestricted airflow path.

The driver side pipe eliminates the factory resonator and middle boot joint, improving durability, while the passenger side features a CNC machined flange and black anodized billet aluminum adapter with double O-Rings for an improved sealing surface. High-quality silicone reinforced boots and stainless-steel T-bolt clamps eliminate blown factory boots and boost leaks that rob horsepower. Finished in a durable Gloss Black powder coat.
