Why Buy from CPP Diesel

Second-Gen Focus: We curate components that package well around 12-valve engine bays and common S300/S400 layouts.
Pro Brands: Diesel-tested hardware from names our customers already run.
Expert Support: Nozzle sizing, controller strategies (boost/MAP), safety switches, and plumbing that avoids leaks and false triggers.
Fast Shipping: Popular injectables and service pieces ship quickly from U.S. warehouses.

Explore the full 1994–1998 Cummins catalog and pair injectables with exhaust and heat control upgrades for safe, repeatable power.

Helpful Notes

Goal first: For towing EGT control, start with water–meth. For short, hard pulls, nitrous adds instant charge oxygen.
Controller choice: Progressive (MAP/boost-based) control delivers smoother on-ramp and safer EGT than simple on/off switches.
Nozzle sizing: Begin conservatively; verify with an EGT gauge and adjust to keep temps in range.
Intercooler sprayers: Great for heat-soak—aim at the core face and protect adjacent wiring/paint.
Safety: Use proper fusing/relays; add low-level cutouts for water–meth and WOT/boost switches for nitrous.

Frequently Asked Questions

Are these kits specific to 1994–1998 Cummins?

Most water–meth, nitrous, and sprayer systems are universal and integrate easily with 12-valves. We curate brands proven on Cummins builds and note any platform details on product pages.

Water–meth vs. nitrous—how do I choose?

Water–meth is ideal for sustained load and EGT control; nitrous delivers a rapid oxygen boost for short pulls or racing. Many street trucks start with water–meth, then add a small nitrous shot later.

Where does the water–meth nozzle go on a 12-valve?

Commonly in the charge pipe before the intake horn; ensure adequate straight length, use thread-seal suitable for methanol, and re-check clamps after the first heat cycles.

Is an intercooler sprayer worth it?

Yes for heat-soak and back-to-back pulls—sprayers (like DEI CryO2) reduce IAT across the core to stabilize power and EGT.

What monitoring should I add?

At minimum, an EGT gauge; add boost and fuel pressure for a complete picture. See Gauges / Related.
