Product Description
The BD DIESEL 1040278 90HP Injector Set is a flow-enhanced exchange injector package engineered to add stronger fuel delivery and improved power to your 1994–1998 Dodge Ram 2500/3500 with the 5.9L 12-valve Cummins. Designed for performance-minded street trucks, towing builds, and weekend horsepower upgrades, this set delivers an estimated 90HP fueling increase while maintaining strong drivability when properly supported with air, exhaust, and pump tuning.
These injectors are built with new VCO Type 145-degree 5-hole nozzles and are calibrated for a high degree of accuracy to improve atomization, throttle response, and power delivery. This set is ideal for customers looking to wake up a stock or mildly modified 12-valve without stepping into aggressive race-only fueling. The kit includes the injector set, tip washers, and a boost orifice elbow fitting for a complete install.
