DESCRIPTION
Product Overview
- This High-Flow Intake Elbow & EGR Delete Kit completely eliminates the leaky EGR cooler while upgrading the necked-down factory elbow to a smooth, mandrel-bent high-flow pipe. It bulletproofs your engine while opening up the air path for instant throttle response.

Key Features
- Premium Billet Construction: CNC-machined anodized black aluminum blocks off the intake ports perfectly. Features premium,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: Will this High-Flow Intake Elbow connect to my aftermarket cold side intercooler pipe?
A: Yes. Our High-Flow Elbow is designed to match the factory connection specs. It will fit perfectly with stock cold side pipe or any aftermarket intercooler pipe designed to connect to the factory intake elbow.
Q: Where does my factory MAP sensor go after deleting the EGR?
A: It stays right where it belongs. On the LLY and LBZ engines, the MAP sensor is located on the intake bridge, not on the EGR components themselves. Our kit is designed to fully clear and accommodate the factory MAP sensor bracket, meaning you don't have to splice, extend, or modify any of your sensor's electrical wiring.
Q: Which exhaust upgrade do you recommend?
A: To maximize your EGR delete, we highly recommend pairing it with our 4" or 5" DP-Back Exhaust Pipe. This straight-pipe upgrade replaces the restrictive factory CAT and muffler, dropping EGTs by another 150°F, unleashing instant turbo spool-up, and giving your Duramax that deep, classic growl.
Q: Do I need to replace my passenger-side Up-Pipe when deleting the EGR?
A: Yes. stock up-pipe has an EGR branch. Simply blocking it off traps exhaust pressure, which eventually cracks the fragile metal bellows (flex section) and causes a major exhaust leak. Replacing it with an EGR-delete Up-Pipe eliminates this failure point permanently.
