FITMENT
- 2007–2009 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
-
The stock 6.7L Cummins EGR loop continuously forces hot, soot-heavy exhaust back into the intake air stream. When this recirculated carbon mixes with crankcase oil vapors, it forms a thick, sticky sludge that chokes intake manifold runners, degrades engine oil, elevates Exhaust Gas Temperatures (EGTs) under load, and subjects the factory EGR cooler to thermal fatigue cracking.
- Engineered to permanently eliminate these failure points, this EGR Delete Kit replaces the restrictive factory hardware with precision CNC-machined block-off plates. By completely sealing off soot recirculation, it supplies your engine with cool, dense air—stopping carbon sludge buildup at the source, dramatically dropping towing EGTs, and restoring lost horsepower and throttle response.
Key Features
- Replace the entire EGR valve, EGR cooler, and intake throttle valve with CNC-machined billet aluminum and stainless steel block-off components.
- Lower sustained exhaust gas temperatures during heavy towing by cutting off the hot exhaust recirculation path at the manifold.
- Unlock faster turbo spool and smoother acceleration by eliminating the intake throttle butterfly — a deliberate airflow restriction designed only for EGR metering.
- Prevent the thick carbon-oil sludge that builds up inside stock intake manifolds when soot-laden exhaust continuously cycles through.
- Rely on pressure-tested TIG-welded joints and leak-tested sealing surfaces on every component, with high-temperature graphite gaskets at each block-off interface.
FAQ
Q: Will deleting the EGR loop really stop carbon sludge from forming in my intake?
A: Yes. The sludge is a direct product of exhaust soot mixing with crankcase oil vapor inside the intake tract. Once you cut off the exhaust recirculation path, the only thing entering your manifold is filtered ambient air — no more carbon paste, no more gummed-up intake ports.
Q: Does removing the throttle valve actually deliver more power?
A: Absolutely. The factory throttle butterfly is there for one reason: to restrict fresh air so the EGR system can force dirty exhaust into the cylinders. Pull it, and your intake tract goes from a choked straw to a wide-open channel. Combined with the EGR delete, you get faster turbo response and a measurable bump in usable power across the rev range.
Q: Will removing the EGR cooler disrupt coolant flow to the rear cylinders?
A: No. The included reinforced coolant bypass hose creates a direct loop around the factory EGR cooler circuit, maintaining continuous, unrestricted coolant circulation to the rear cylinder bank where it’s most critical. Without it, you’d create a dead leg in the cooling system — this hose prevents that entirely.
Q: Do I need an ECU tune to run this kit?
A: Yes. Both the EGR valve and throttle valve are monitored by the engine control module. Without a supporting delete tune, the ECU will detect missing components and trigger a check engine light — potentially sending the truck into reduced-power limp mode. A proper custom tune is mandatory for full functionality.
