1998.5-2002 Cummins Bosch New 40HP RV275 Injector (0432193635-IIS)

The 0432193635-IIS is a brand-new Bosch 40HP-over-stock performance injector for the 1998.5-2002 5.9L 24V Cummins running an RV275 mid-range injection pump. These are not remanufactured — they're 100% new Bosch hardware, which means no core charge and no waiting for a rebuild. Pop-off pressure is set to 300 BAR, which delivers a measurable horsepower and torque bump over the OE 275HP mid-range setup.

This is the entry-level performance injector for the 24V VP44 platform — a mild upgrade that adds power without requiring a different injection pump, lift pump, or tuning. Owners report better mid-range pull and stronger throttle response, especially on trucks running a tuner or mild module. The injectors cross-reference to Cummins OE part numbers 3944183 and 3944184.

Sold individually; a 24V Cummins uses six total. Order quantity to match.
