6.7 Cummins Performance Kits

Why Does Your 6.7 Cummins Need Performance Upgrades?

EGR Soot Contamination

The factory EGR loop sends hot, abrasive soot straight into your intake manifold. Over time, that carbon cakes the intake, sticks the throttle valve, and dirties the engine oil. A delete kit removes the source entirely so the motor breathes clean, hot-free air.

Cylinder 6 Thermal Hot Spots

The 6.7L cools the front cylinders better than the rear, leaving cylinder 6 running hot under heavy tow loads. A coolant bypass kit builds a secondary flow path to equalize head temperatures and protect the head gasket from thermal stress. Pair either fix with a grid heater upgrade for 6.7 Cummins so the intake heater stays reliable through cold starts.

Restricted Air and Exhaust Flow

Stock intake horns, plastic intercooler boots, and the dense factory DPF choke the engine. Swapping in a high-flow intake, free-flowing exhaust, and a proper tune unlocks the horsepower the engine was built to make. For a fully stripped intake, our grid heater delete kit for the 6.7 Cummins pulls the heater element out for an open plenum.

What Can 6.7 Cummins Performance Kits Solve?

Component-Level Solutions

Each kit targets a specific failure point. Deletes eliminate soot and backpressure. Coolant and transmission bypass kits manage heat. Tuning hardware keeps the ECU happy after parts are removed. Induction and fuel upgrades feed the cylinders what they need under load. Together they add up to a truck that pulls harder, runs cooler, and lasts longer.

FAQs about 6.7 Cummins Performance Kits

What does a 6.7 Cummins performance kit include?

A 6.7 Cummins performance kit targets the factory weak points on the Ram 2500 and 3500 platform. The core upgrades are EGR and DPF deletes, a CCV reroute, a coolant bypass, and the tuning hardware that keeps the ECU happy after parts come off.

Depending on the bundle you pick, you can add cold air intake, intercooler pipes, a billet compressor wheel, fuel rail plugs, and filtration. Each piece is built from CNC 6061-T6 aluminum, T304 stainless, and Viton sealing so it survives brutal duty cycles.

Which trucks do these 6.7 Cummins kits fit?

The deletes and coolant kits span the full timeline. Early trucks from 2007.5 to 2009 use the first-gen EGR cooler delete, while 2010 to 2014 trucks get the EGR cooler throttle valve and DPF muffler deletes.

The late-model 2013 to 2019 Ram 2500, 3500, 4500, and 5500 take the black-edition EGR delete, and the 2019 to 2024 trucks use the tuner harness plug kit. Cab and chassis 3500 and 4500 are covered from 2013 to 2018.

Do I need a tuner with an EGR or DPF delete?

Yes. Removing the EGR, DPF, or DEF hardware triggers fault codes and limp mode unless the ECU is recalibrated. A delete tune or SOTF switch shuts off the related sensors and unlocks the power the restriction was hiding.
Pairing a tuner harness plug kit with the delete keeps the CAN bus closed and prevents water or corrosion at the unplugged connectors under the truck.

Will a cold air intake or intake horn help my 6.7 Cummins?

A high-flow cold air intake and smooth intake horn remove the restrictive bends and baffles in the factory air tract. More air volume and velocity into the cylinders means stronger spool and cleaner combustion under load.
These intake upgrades pair naturally with a delete and tune, but they are street-legal and do not require emissions modifications to install.

What does the coolant bypass kit do for the 6.7 Cummins?

The 6.7L runs the rear cylinders hotter than the front, and cylinder 6 is the classic head gasket failure point under heavy towing. The coolant bypass hose barb adapter builds a secondary flow path to equalize head temperatures.
It is a simple bolt-on that dramatically cuts thermal hot spots, and the leaking repair kit refreshes the notoriously soft factory barb adapters at the same time.

Can I run a bigger turbo or billet wheel on a stock truck?

A drop-in billet compressor wheel or a non-VGT turbo upgrade spools faster and moves more air, but it pays off most after deletes and fuel tuning are in place. A billet wheel is a direct swap into the stock Holset housing.
If you push past moderate boost, add head studs and a fuel pressure upgrade so the bottom end keeps up with the extra air.

What fuel system upgrades improve 6.7 Cummins reliability?

A solid fuel rail plug stops the pressure relief valve from popping during aggressive tuning, and a big-line fuel rail kit adds internal volume for steady pressure.
Premium fuel filters and a water separator catch moisture and debris before they reach the high-pressure common rail, protecting expensive injectors on high-mileage trucks.

What is the CCV reroute and why delete it?

The crankcase ventilation system pushes oily vapor into the turbo inlet, coating the compressor wheel, intercooler, and intake with sludge. The CCV reroute kits send that vapor away from the intake path entirely.
Less oil in the boost side means cleaner combustion, a happier turbo, and fewer stuck VGT vanes from soot buildup.

Are these 6.7 Cummins performance kits legal for street use?

EGR, DPF, and CCV delete components are engineered for competition and closed-course off-road use only. Federal emissions compliance is the responsibility of the vehicle owner, and street use of deleted trucks may violate local laws.
Our coolant bypass, tuner harness plugs, and intake hardware are street-legal upgrades. Every order includes Free Shipping, a 1-year warranty, and a 45-day return policy so you can build with confidence.

How hard is installation and what warranty is included?

Most deletes and coolant kits bolt on with basic hand tools and a weekend in the driveway. The EGR delete drops the cooler and blocks the ports, the CCV reroute reroutes a hose, and the harness plug caps the connectors.
Every part is covered by Free Shipping, a 1-year warranty, and our 45-day return policy if it is not the right fit for your build.
