Description

This Stage 2 upgrade combines a Stage 1 High Flow Bundle and Stage 2 intake Kit to increase airflow for the turbo and engine, improving efficiency, throttle response, and turbo spool up. It replaces restrictive factory plastic parts with high flow fabricated intake pipe, intake horn, and air box enclosure with dry filter assembly. It features large diameter 4 in. piping with smooth aerodynamic bends, 14 ga. aluminum construction, and a 4.8 in. turbo intake horn (20% air flow improvement over stock). The kit also upgrades the restricted 2.5 in. diameter driver (hot) side intercooler pipe and leak-prone plastic/rubber passenger (cold) side pipe with WCFab's heavy duty 3 in. diameter 1-piece Driver (Hot) Side and 3.5 in. diameter Passenger (Cold) Side LBZ Intercooler Pipes. It also includes a 3" Y-Bridge Kit that replaces the OEM upper intake manifold. CNC machined flanges with double o-ring seals provide improved sealing. It retains factory connection points and sensors, requires no tuning, and is a bolt-on installation. Custom powder coat finish is available. Made in the USA.
