Wehrli Custom Fab Y-Bridge Kit 01-04 GM 6.6L Duramax LB7
Need more air? Your stock intake manifold can be restrictive, making bottlenecks in your air intake system which robs you of performance! Grab Wehrli's Y-Bridge kit that can increase airflow by up to 50% so your engine gets to breathe free.
NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.
Wehrli's Y-Bridge Kit comes with their high flow 3” kit to increase throttle response and turbo spool up by creating a full 3" intake tract from the intercooler outlet to the engine. Eliminates the angled OEM intercooler boots that are prone for failure. Includes FPRV Block off kit to allow proper clearance to larger diameter Y-bridge.
TURBOCHARGER NOTE:
NOT RECOMMENDED FOR USE WITH S300 OR S400 STYLE TURBOCHARGERS. If you are planning to run a turbo other than an OEM / IHI style upgraded drop in on your setup, please check out our S300 Single Turbo Kit WCF100478 and our S400 Single Turbo Kit WCF100489 or call us for help placing your order.
Fitment Note:
2001 models have the MAP sensor installed on the intake runner rather than the bridge from the factory. Due to the increased size of our bridge over stock, in order to install this kit you will need to relocate the MAP sensor to the port on the new bridge assembly and then drill and tap the runner to install a pipe plug (not included) in the original MAP port location (or source a new intake runner from a later model 02-04 LB7 truck).
