Description
You may not know this but your truck burns more than just diesel. With each cycle of the piston, you burn both diesel and air which both are required for power. If you are still using your stock intake manifold it can be restrictive, making bottlenecks in your air intake system which robs you of performance! Grab Wehrli's High Flow 3" Y-Bridge Kit gives you a 36% improvement to airflow over Stock so your truck is never out of breath.
NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.
Wehrli's High Flow 3" Y-Bridge Kit comes with 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. 3" high flow upper and lower intercooler pipes feature smooth flowing mandrel bends, CNC machined billet flanges and perfectly compliment the y-bridge to offer a full 3" tract from intercooler pipe slip connection to the engine incorporating the factory grid heater and EGR connection controls.
What does more airflow mean? It means you get the most out of your engine in terms of performance and efficiency. If you have done or are planning any performance upgrades like injectors and fuel pumps it is essential you clean up your airflow or all those upgrades will be "up in smoke."
