This LBZ 3" Y-Bridge Kit is an upgraded high flow intake kit for the 2006-2007 LBZ Duramax which 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 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. 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. Compatible with OEM lower passenger side intercooler pipe as well as our upgraded 3.5" High Flow Passenger Side Intercooler Pipe Kit WCF100367. Finished in your choice of custom powder colors. This product is compatible with stock trucks requiring no additional modifications, upgrades, or tuning for installation. Pairs best with emissions compliant tuning and drop in turbochargers for optimum performance gains.

K&N Inlet Boost Tubes run from the air intake to the turbo and are designed to increase airflow by removing the restrictive sections of your stock inlet tubes. This guarantees an increase of airflow to the turbos for faster spooling and more power. Pairing K&N’s inlet tubes with a K&N intake will give the vehicle even more performance benefits.

• All required hardware is included

When installing he X-Flow Intake and Open Grid Plate in a Cummins, the factory grid heater is removed. By adding the BD X-Flow Air Intake Heater Kit to your X-Flow Intake you can take advantage of quicker, cleaner cold starts.

• Heater for BD Intake Horns (p/n 1041560 / 1041561 / 1041566) when installed with Intake Open Grid (p/n 1041562 / 1041564)
• Heater For BD Intake Horns PN/1041560/1041561/1041566 When Installed w/Intake Open Grid P/N/1041562/1041564
• Aids Cool and Cold Weather Starting
• Connects To Stock Grid Heater Wire

Improve your throttle response with BDs large bulbous intake plenum which holds extra reserve air available to improve turbo response time on acceleration. The smooth radius turns reduces air flow turbulence. BDs unique design positions the fastening bolts outside of the intake (instead of through it) also reduce airflow turbulence. The improved turbo response time can be measured with HP when calculating time to speed. Two convenient ports (one pre-tapped) make it easy to monitor boost and/or inject nitrous oxide or another power adder. Now available in both black powder coated and highly polished aluminum finishes. Use it with one of our X-Intake air systems for even greater airflow!

• Two convenient ports (one pre-tapped) make it easy to monitor boost and/or inject nitrous or other power adder
• Smooth radius turns to reduce turbulence and intake pressure losses
• Smooth Radius Turns To Reduce Turbulence And Intake Press. Losses
• Two Ports One Pre-Tapped Make It Easy To Monitor Boost
