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.

• 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.
