Step 1 :

Disconnect the mass air flow sensor. Remove the intake tube by loosening the hose clamps on the intake tube.Disconnect all coolant lines leading to the EGR cooler. Now the entire EGR assembly can be pulled out. Be sure to keep the exhaust gasket for installing the baffle.

Step 2 :

Pre install the charging tube using the provided baffle with O-ring.Note: Be sure to install two longer bolts on the front side of the pipe.

Step 3 :

1.Install the provided bracket onto the motor using a factory bolt and the M10 x 20 hex head bolt provided in the kit.
2.Install the exhaust block using the provided 20mm and 30mm bolts. All bolts will be installed from the back of the baffle.

Step 4 :

1.Re-install intake tube with the front long bolts going through the previously installed support bracket.
2.Reverse earlier steps to re-install the pcv hose, electrical wires, intake and intake resonator.

Step 5 :

1.Use the newly provided coolant hose and hose adapter to connect the two coolant ports previously connected to the EGR cooler. Secure the hose with the provided hose clamp.
2.Replace the manifold bolts with the provided vertical bolts.

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 2006–2007 LBZ is widely considered the holy grail of Duramax engines. Free of complex emissions traps like DPF, it’s a pure performance beast—with one massive exception: the EGR system.
Over time, the factory EGR dumps burning-hot, abrasive soot into your clean intake, choking your engine with power-robbing sludge. Worse, the factory cooler is prone to internal cracks that leak coolant into your cylinders—often leading to catastrophic blown head gaskets.
This LBZ EGR Delete Kit completely removes this bottleneck. allows your LBZ to breathe pure, cold air, extending engine life and lowering operating temperatures.

Key Features

Premium Billet Construction: CNC-machined anodized black aluminum blocks off the intake ports perfectly,leak-free seal under high boost.
Lower EGTs & Coolant Temperatures: By completely bypassing and deleting the hot EGR cooler, you drop EGTs and take the thermal load off your truck’s cooling system.
Quicker Turbo Spool-Up: Freeing up your intake restriction allows clean, fresh air to flow without turbulance. You'll feel a crisper, more instant throttle response when pulling heavy loads.
Better Fuel Mileage: When your diesel doesn't have to re-burn dirty exhaust soot, combustion efficiency peaks—giving you more miles out of every tank.

FAQ

Q: What is the difference between this LBZ kit and the LLY kit?

A: The layout is completely different. The LLY requires bypassing a buried cooler and has different flange shapes. The LBZ kit includes dual billet block-off plates with built-in O-ring seals that fit the LBZ’s specific dual-intake design perfectly. Always buy the kit matching your exact model year.

Q: Will I get a Check Engine Light on my LBZ after installing this?

A: Yes. Removing the EGR valve on an LBZ will throw emission-related diagnostic codes. You must use an aftermarket tuner with an EGR-delete tune to disable the codes and prevent the truck from going into "limp mode."

Q: Why does this kit include an "Intake Support Bracket"?

A: Removing the bulky factory EGR cooler also removes the stock support points for your intake plumbing. Our kit includes a heavy-duty stainless steel support bracket to keep your intake tube secured and prevent vibration-induced stress on your engine fittings.

Q: Can I reuse my factory gaskets?

A: No need. Our kit includes high-temperature, fuel-resistant O-ring seals pre-fitted into the billet aluminum intake block-off plates. This guarantees a far better, more reliable pressure seal than old, compressed factory gaskets.
