INJECTABLES — 2013–2018 DODGE RAM 6.7L CUMMINS

Add safe, controllable power and bring down EGTs on your 6.7L Cummins with proven water–methanol and diesel nitrous solutions. This subcategory lives under 13–18 6.7L CUMMINS and is curated by CPP Diesel’s Cummins experts for towing, street performance, drag racing, and sled pulling.

All Injectables — 13–18 6.7L Cummins

Note: Some items are universal fit (water–meth kits, nitrous systems, CO₂ intercooler sprayers) and integrate cleanly on 6.7L engine bays with proper routing, wiring, and safety controls.

Why Add Injectables?

Reduce EGTs under load: Water–methanol can drop exhaust temps to protect pistons, turbine, and manifold during towing or competition.
On-demand power: Diesel nitrous systems provide tunable horsepower for drag racing/sled pulling with progressive control hardware.
Improve charge-air density: Intercooler sprayers can knock down IATs ahead of the intake horn for short pulls and hot-day towing.

Recommended Supporting Mods

Air Intake Systems & Filters (13–18) — maximize airflow for cooler, denser charge air.
Intercoolers & Boost Tubes (13–18) — improve CAC efficiency and reliability.
Exhaust System & Components (13–18) — reduce backpressure and heat.
Cooling System (13–18) — keep temps stable during sustained load.
Engine Parts (13–18) — head studs, gaskets, and reliability upgrades.
Fuel Filtration (13–18) — clean fuel supply for consistent performance.

Install & Tuning Notes

Plumb water–meth nozzles post-intercooler with failsafes (flow/pressure) and use progressive controllers based on boost or MAP for smooth delivery.
Use a dedicated reservoir and quality lines; verify zero leaks and secure routing away from heat and moving parts.
Nitrous setups should include bottle heater, WOT/window switch or progressive controller, and proper safety solenoids.
After any change, log EGT, boost, and timing; increase doses gradually and verify under real load.
Emissions/usage: Race-only parts must be used solely in sanctioned competition where legal. Check local and federal regulations.

Frequently Asked Questions

Will water–methanol help my 6.7L Cummins when towing?

Yes—when properly set up, it can lower EGTs on long grades and help maintain speed with less downshifting. Start conservatively and monitor EGTs.

What mix ratio should I run?

A common starting point is 50/50 water–methanol by volume for cooling and knock resistance; always follow the kit maker’s guidance and tune by data (EGT/IAT).

Do I need additional gauges or monitoring?

We recommend EGT and boost monitoring and, ideally, a controller with flow-failsafe to cut injection if flow drops or boost falls unexpectedly.

Is diesel nitrous street-legal?

Nitrous systems and some water–meth hardware are intended for competition use only where permitted. Verify local laws before purchase and installation.

What other parts pair well with injectables?

High-flow intake, efficient intercooler/boost tubes, low-restriction exhaust, healthy fuel filtration, and sound engine sealing (head studs/gaskets) complement injectables for safe gains.
