DDP DDP9498-DF 94-98 5.9L 12V CUSTOM DUAL FEED INJECTOR SET -

The code DDP9498‑DF refers to a Dynomite Diesel Dual‑Feed injector set designed specifically for the 1994–1998 Dodge Ram Cummins 5.9L 12‑valve P‑Pump engine.

 Key Features

Engine Compatibility

• Designed for 1994–1998 5.9L Cummins (12‑valve) engines.

True Dual‑Feed Design

• Engineered from the ground up as dual‑feed injectors—not simply OEM injectors modified. This results in tighter machining tolerances, fewer inconsistencies, and better long-term durability .

High‑Performance Nozzle

• Features a multi‑angle needle valve with DLC (Diamond-Like Carbon) coating, optimized for "extreme fuel delivery and massive pressure"

Power Handling

• Capable of supporting 1,200–1,400 RWHP, making it suitable for high‑power, competition-level builds.

Custom Built & Matched Set

• Sold as a matched set with no core charge once a race waiver is completed. Custom-sized internally to match your specific application.

Lead Time

• Expect a manufacturing time of about 1 week, since these are built to order.

No Warranty / Racing Use Only

• There is no warranty or returns, and these injectors are not street legal. They are strictly for competition use and not sold in California due to emissions regulations .

 Is This Right for You?

 Suitable if you are building a high-horsepower racing or competition Cummins setup, and have:

• A P‑Pump system with at least a 12.5 mm plunger for proper fuel supply.

• Support systems such as upgraded fueling, turbo, tuning, etc.

 Not recommended if:

• You’re using your truck for street driving, towing, or aren’t targeting 1,200+ RWHP.

• You prefer products with warranty or return options.

• You live in California (not available due to emissions regulations).

If your needs are less extreme, consider Stage 2, 3, or 4 injector sets from Dynomite, which offer varying power levels (e.g., ~550 RWHP for Stage 2, ~700–750 RWHP for Stage 3) with warranties and street compatibility.
