Wehrli Custom Fabrication WCF100323-GM Stage High Flow Intake Bundle Kit LBZ Duramax - 1 2006-2007

The Wehrli Custom Fabrication Stage 1 High Flow Intake Bundle Kit is a comprehensive performance upgrade designed for 2006-2007 GM 6.6L LBZ Duramax engines. This Stage 1 upgrade improves airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool-up while eliminating weak points in the factory design that can lead to boost leaks or complete failures in hard-working and high-performance applications.

Y-Bridge System:

The 3" Y-Bridge Kit replaces the OEM upper intake manifold supplying air to the engine intake runners. The OEM Y-bridge for these trucks is a poorly designed, slip-fit style two-piece bridge with very little support and is prone to blowing apart under boost on hard-working and high-performance trucks creating poor drivability, reduced fuel economy, and decreased power. This kit is a much improved, high flow, bolt together style two piece 3" bridge which provides a secure sealing surface where the air inlet horn connects to the bridge.

Key Features:

• WCFab's Signature 3" Two Piece Y-Bridge with Upper Crossover and Lower Intercooler Pipes flows 36% better than stock
• 3" Hot (Driver) Side Intercooler Pipe with high temperature wire-reinforced boot
• 3.5" Cold (Passenger) Side Intercooler Pipe flows 47% better than stock
• Mandrel bent smooth flowing intercooler pipes with CNC machined billet flanges and 14ga. aluminum intercooler piping
• CNC machined flanges with double O-ring seals, supplied with new wire clip rings for both slip flanges
• Upgraded silicone hump boot with stainless steel t-bolt clamps to withstand higher boost pressures than stock
• Available in multiple custom powder coat finish options
• Made in the USA

This kit pairs best with emissions-compliant tuning and drop-in turbochargers for optimum performance gains. The Stage 1 Bundle eliminates restrictive factory components and increases reliability while delivering improved throttle response and enhanced turbo spool-up for your LBZ Duramax.

Note: This product cannot ship to the state of California. CSF Aftermarket intercoolers require modification/grinding of intercooler outlet lip for installation.
