Step 1 :

1.Disconnect batteries.Remove the passenger side inner wheel cover to drain the engine coolant, and disconnect the lower radiator pipe by removing the metal clip.
2.Remove the intake pipe from the filter to the plastic turbine interface.Gently pry out three rubber washers and remove the bellows and filter.

Step 2 :

Install the new exhaust block O-plate using the factory gasketand provided bolts. Two M8 x 20hexagon head bolts will be screwedin from the back, and two M10 x 20hexagon head bolts will secure the bracket in place.

Step 3 :

1.Remove the plastic cover from the wiring harness and plug the wiring harness under the new inflation tube.
2.Install a new intake pipe. Slide the tube into the rubber tube and tighten the bent end with bolts.

Step 4 :

Transfer the pressure sensor from the raw material filling tube to the new filling tube. The installation bracket needs to be rotated 1800 on the sensor in order to be installed onto the new inflation tube.

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 2007.5–2010 LMM Duramax is a workhorse, but its factory intake is a massive bottleneck. The stock setup forces hot exhaust and oily PCV mist into a narrow elbow with a bulky throttle valve—creating a thick, sticky sludge that chokes your engine and kills throttle response.
Even worse, the stock LMM EGR cooler is a ticking time bomb. It is highly prone to internal thermal cracking, allowing coolant to slip into your cylinders and blow your head gaskets.
Our High-Flow Intake Elbow & EGR Delete Kit solves both issues at once. It completely deletes the cracked cooler risk while swapping out the choked-up factory elbow for a seamless, wide-open high-flow pipe.

Key Features

Heavy-Duty Construction: CNC-machined from 6061 billet aluminum and high-grade stainless steel. Premium high-temp O-rings ensure a lifetime, leak-free seal even under high boost.
Massive Airflow Boost: Ditches the restrictive factory butterfly throttle valve, increasing fresh air intake flow by up to 80% for instant throttle response.
Lower EGTs & Coolant Temperatures: By routing hot exhaust away from the engine, EGTs drop, and your entire cooling system runs significantly cooler.
Built-in 1/8" NPT Port: The aluminum elbow features a pre-tapped 1/8" NPT port with a flush plug—making it effortless to install a boost gauge, water-methanol, or nitrous nozzle.

FAQ

Q: What is the difference between this "High-Flow Kit" and the standard LMM EGR Delete Kit?

A: The standard kit only blocks the EGR, leaving the restrictive stock elbow and butterfly valve in place. This High-Flow Kit replaces that entire bottleneck with a wide-open, mandrel-bent pipe—increasing airflow by 80% for faster turbo spool-up and crisper throttle response.

Q: What is the pre-tapped 1/8" NPT port on the intake elbow used for?

A: It is a built-in expansion port for easy upgrades. Use it to directly mount an aftermarket boost gauge, water-methanol, or nitrous nozzle without drilling into your new aluminum elbow. If you don't need it, just keep the included flush plug bolted in tight.

Q: What happens to the stock butterfly throttle valve electronics after installing this elbow?

A: Since High-Flow Elbow completely removes the restrictive factory butterfly valve, you will simply unplug the electrical connector going to the factory valve actuator. Be sure to wrap the open truck-side harness plug with high-quality electrical tape or cover it with a heat-shrink cap to protect it from road debris, dust, and moisture.

Q: Why should I upgrade my turbo downpipe while installing the LMM EGR delete?

A: Factory downpipe is crushed into a restrictive "pancake" shape behind the turbo. Upgrading to 3" High-Flow Downpipe eliminates this bottleneck—dropping EGTs by an extra 50°F to 100°F, speeding up turbo spool, and letting your engine breathe freely.
