1994-1998 Cummins R4 6 x .018 140° Injector (SAC) (0432131715-R4)

Bosch R4 SAC race injector for 1994-1998 Dodge Ram 2500/3500 5.9L 12V Cummins. 6 x .018 nozzle with a 140° spray angle — built for high-output performance builds running up to roughly 1000 HP, with the SAC tip geometry and tighter spray pattern that race and pulling trucks need to atomize at high rail pressure.

This is a competition-grade injector. The 6x.018 nozzle size and 140° spray angle are matched for high-RPM, high-airflow setups where stock spray geometry and smaller nozzle sizes leave fuel on the table. The narrower spray cone keeps fuel off the cylinder wall in a high-boost combustion chamber.

Requires a 12mm Dragon Fly / Dragon Flow Pump to feed properly — stock P7100 fueling cannot keep up with this injector size at the RPM and rail pressure these are designed for. Sold individually so you can buy six for a full set or one for a single replacement.
