FITMENT
- 2007.5-2009 6.7L Dodge Ram Cummins 2500 3500 Turbo Diesel.
- Note: This is for pick up only; Does NOT fit Cab & Chassis trucks.
- The base kit does not include DEF tank plugs.
DESCRIPTION
Product Overview
- Unshielded factory sensor plugs hanging under the frame and hood present a major reliability risk once stock emissions components are tuned out on 6.7L Cummins platforms. Exposed socket pins quickly trap moisture and road grime, leading to severe corrosion and hard-to-diagnose wiring failures.
- Shield your unused factory wiring with this complete 6.7L Cummins Sensor Plug Protection Set. Engineered to click directly into your disconnected OEM connectors, these sealed weather-pack caps block water and road debris, eliminate corrosion risks, and maintain a neat, professional look under the hood.
Key Features
- Molded from heat-resistant, high-impact ABS polymer that takes harsh under-hood conditions in stride.
- Keeps moisture, dirt, road grime, and engine heat away from pricey OEM wiring, stopping corrosion and shorts.
- Seals up the open harness connectors left dangling after you flash aftermarket performance tunes.
- Uses factory-grade locking tabs and internal rubber seals, so each cap seats snug and stays put instead of vibrating loose.
FAQ
Q: What’s the point of harness plugs after adding performance upgrades?
A: Once factory parts are removed or bypassed, certain electrical connectors stop being used. Protective plugs keep those connectors sealed so they don’t sit exposed to the harsh engine bay over time.
Q: Can these plugs clear Check Engine Lights all by themselves?
A: No. They’re physical weather caps with no resistors or logic circuits to bypass ECM codes. You’ll need an aftermarket tuner to switch off the diagnostic trouble codes.
Q: Do these plugs work alongside EGR/DPF delete mods?
A: Absolutely — this kit is built specifically for trucks getting an EGR and DPF delete. As the factory emissions parts come off, these plugs seal and shield the exposed, disconnected connectors so they stay clean, dry, and safe from corrosion and short circuits.
Q: Do these have to go on before I tune the truck?
A: No. They’re a protective accessory, so you can fit them before or after tuning. Their job is just to cover the unused connectors once the factory components are out of the circuit.
