FITMENT
- 2010–2024 6.7L Dodge Ram Cummins 2500 / 3500 Pickup Turbo Diesel.
- Note: Does NOT fit Chassis Cab 3500 / 4500 / 5500 models.
DESCRIPTION
Product Overview
-
Factory 6.7L Cummins intake tracks are severely restricted by redundant throttle valve assemblies and high-temp EGR loops that dump dirty exhaust directly back into incoming air. As soot mixes with oil vapor, sticky carbon sludge chokes intake ports and valves, while thermal stress causes the thin-walled internal tubes of the OEM EGR cooler to crack—risking sudden coolant loss and engine-destroying hydro-lock.
- Purpose-built to eliminate both thermal and mechanical restrictions, this complete upgrade kit replaces the factory EGR and throttle valve hardware with smooth-bore, CNC-machined components. By removing the primary intake bottleneck and permanently sealing off soot recirculation, it guarantees clean, dense charge air delivery, lowers operating temperatures, and completely removes the threat of internal cooler leaks.
Key Features
- Includes a pre-tapped 1/8" NPT port directly on the exhaust plate, enabling effortless, direct installation of your aftermarket Exhaust Gas Temperature sensor probe.
- Features a reinforced coolant reroute line that preserves seamless engine coolant circulation, eliminating localized hot spots and maintaining stable operating temperatures.
- Prevents gummy carbon deposits and oil mist from restricting intake pathways or degrading engine oil quality.
- Shields critical internal components from premature wear and fouling, ensuring peak performance and extended engine reliability over time.
FAQ
Q: What do I gain by also deleting the throttle valve instead of just the EGR cooler?
A: The throttle butterfly is a deliberate intake restriction that exists only to create a pressure differential for EGR metering. Removing it along with the EGR system gives you a straight, unrestricted intake path. The turbo spools faster from a stop, throttle input translates to acceleration more immediately, and the engine isn’t fighting a built-in airflow choke on every intake stroke.
Q: Does the coolant bypass installation require bleeding the cooling system afterward?
A: Yes. Since the bypass hose installation requires opening the factory coolant circuit, you’ll need to refill coolant to the correct level and bleed any trapped air pockets from the system. Skipping the bleed step can create vapor pockets that interfere with coolant circulation and potentially cause localized overheating. Take your time on this step — it’s critical.
Q: What kind of performance gain can I expect when pairing this delete with an upgraded intake horn?
A: The EGR delete stops the soot and contamination cycle; a high-flow intake horn addresses the airflow side. Together, you eliminate the two biggest breathing restrictions on the 6.7L. Expect noticeably reduced turbo lag, sharper off-idle throttle response, and an additional 50–200°F drop in sustained towing EGTs compared to the delete alone.
Q: Does removing the EGR cooler create cooling system problems or hot spots in the block?
A: No. The included silicone coolant bypass hose is engineered to carry full coolant flow through the same circuit path — just routed around where the cooler used to sit. The block continues to receive uniform coolant circulation, and removing the EGR cooler actually eliminates a heat source that was dumping exhaust-temperature thermal load directly into the cooling jacket.
