Step 1 :

Unlock the charge pipe by using a large flathead screwdriver to turn the locking ring counter clockwise. Place the tip of the flathead screwdriver into the groove on top of the locking ring, and push it toward the passenger side while pulling forward on the charge pipe by hand.

Step 2 :

1.Remove the zip tie seuring the wire harness to the stock intake bridge. 2.Using a 10mm socket,remove the two Hose clamps securing the rubber hoses to the intake bridge.

Step 3 :

1.Remove the stock intake bridge from the engine.Using a 10mm socket,remove the pressure sensor from the stock intake bridge.
2.Install the pressure sensor to the Diesel intake bridge of the supply kit.

Step 4 :

1.Using the 12mm socket,remove the bolt securing the EGR crosscover tube.Install the supply intake bridge and restall the bolt from the previous step hand tight.
2.Secure the intake bridge flange to the motor with the supply M8 allen bolts.

Step 5 :

1.Using a 12mm combination wrench, tighten the bolt that was installed hand tight,This will re-secure the intake bridge and the EGR crossover tube.
2.Reconnect the wire to the pressure sensor on the Sinister Diesel Intake Bridge. The hoses can be secured to the new intake using the provided long alen bolts, spacers, and at washers. 3.Replace the gaskets that go before and after the heater grid. Be sure they are placed in the proper location and direction. Using a socket, reinstall the throttle valve and heater grid.

Step 6 :

1.Install the bracket. The M10 bolt will be screwed into the support bolt. Secure the transmission dipstick to the bracket using 1/4-20 bolts, nuts, and washers.
2.The bracket will hold the coolant hose connector in place.

DESCRIPTION

Product Overview

The 2011–2015 6.6L LML Duramax is a legendary powertrain, pulling massive loads with ease. However, because it was built during an era of rapidly tightening emissions standards and strict cabin-noise requirements, GM engineers had to make major sacrifices in under-hood packaging.
The High-Flow Intake Bridge solves this by replacing these restrictive parts with a wide-diameter, By deleting the weak resonator and smoothing the airflow path, this kit drastically reduces air turbulence, lowers EGTs, and helps turbo spool much faster.

Key Features

Premium Material: Features CNC-machined billet flanges and hand-crafted TIG welds. Pressure-tested to ensure a leak-free seal under high boost.
Boosts Airflow by 80%: Replaces the choke point of the stock intake with a wide-diameter, large-radius mandrel-bent aluminum tube, allowing air to flow freely into the engine.
Lowers EGTs: By significantly increasing intake air volume and velocity, this kit promotes more efficient combustion, dropping EGTs under heavy towing or high-performance conditions.
Sharpens Throttle Response & Quicker Spool-Up: With a smoother, less restrictive path, your turbocharger builds boost much faster. This minimizes turbo lag and delivers immediate off-the-line torque.

FAQ

Q: What is the main purpose of deleting the factory resonator?

A: The OEM plastic resonator box easily cracks from constant heat and vibration, causing boost leaks and power loss. Deleting it with our solid aluminum block-off plate permanently eliminates this failure point, ensures stable boost pressure, and releases a clean, subtle turbo whistle.

Q: How does this intake bridge help lower my EGTs?

A: The restrictive factory elbow starves cylinders of fresh air, spiking EGTs under load. By boosting airflow by up to 80%, this kit ensures a cooler, more efficient burn—making it an essential upgrade for heavy towing.

Q: Can I install this kit if I still have my factory EGR system active?

A: While this kit physically fits a stock EGR setup, factory EGRs still introduce abrasive soot into your engine. Combining intake bridge with EGR delete is the ultimate setup—maximizing airflow while keeping your new, high-flow piping completely soot-free.

Q: What are the symptoms of a failing factory LML intake elbow?

A: If your stock plastic resonator has hairline cracks or failing seals, you will experience power-robbing boost leaks. Upgrading to our solid aluminum kit permanently eliminates these failure points, restoring your throttle response and towing power.
