DESCRIPTION
Product Overview
- The combination of a necked-down factory intake elbow and a failure-prone EGR cooler limits performance and creates severe reliability risks. Tight stock intake geometry restricts incoming air volume and slows down spool times, while the OEM EGR cooler remains highly susceptible to internal cracking and coolant leaks.
- Upgrade to this High-Flow Intake Elbow & EGR Delete Kit to open up your engine's intake tract and protect it from costly failure. Featuring a free-flowing, mandrel-bent aluminum intake pipe paired with complete EGR removal hardware, it prevents coolant leaks, restores crisp throttle feel, and feeds your engine the clean, unrestricted air it needs.
Key Features
- Seal Off the Intake Ports for Good: Precision block-off plates, CNC-cut from black-anodized aluminum, clamp the intake ports shut so boost pressure stays put behind a leak-free, dependable seal.
- Cool Down the Whole Engine Bay: With the hot EGR cooler bypassed and deleted, exhaust gas temperatures drop and the thermal stress on your truck’s entire cooling system lets up.
- Spool the Turbo Up Faster: Clearing the intake restriction lets clean, fresh air stream through with zero turbulence, so the throttle snaps to attention the instant you ask for more power under load.
- Stretch Every Tank of Fuel: Stop the engine from re-burning dirty soot and combustion efficiency climbs, turning more of each gallon into forward motion instead of waste heat.
FAQ
Q: Is this High-Flow Intake Elbow compatible with aftermarket intercooler pipes?
A: Yes. Designed to factory inlet dimensions, our intake elbow connects seamlessly with either your stock cold-side intercooler pipe or any aftermarket intercooler piping built for OEM-spec fitment.
Q: What happens to the factory MAP sensor when removing the EGR assembly?
A: It remains safely in its original position. On LLY and LBZ Duramax engines, the MAP sensor resides on the intake bridge rather than the EGR valve itself. Our kit is precision-engineered to clear the sensor bracket completely—no wire splicing, extending, or harness modifications required.
Q: Should I combine this EGR delete with a CCV/PCV reroute kit?
A: Absolutely — together they form the ultimate clean-air combo. Deleting the EGR stops dry carbon soot, while a CCV/PCV reroute stops wet oil mist from reaching the intake, so combining the two guarantees a clean, dry, restriction-free intake. For the matching upgrade, see the 2004-2010 6.6L Duramax CCV/PCV Reroute Kit.
Q: Which exhaust setup best complements this EGR delete kit?
A: For optimal performance, we strongly recommend pairing this kit with a 4" Downpipe-Back Performance Exhaust. Eliminating restrictive factory mufflers and catalytic converters lowers Exhaust Gas Temperatures (EGTs) by up to 150°F, sharpens turbo spool, and delivers a deep, throaty exhaust note.
