R5237650 “7650's” – Premium 12.7L Detroit Series 60 Injectors

R5237650 injectors—commonly known as “7650's”—were originally installed in the Premium 12.7L Detroit Series 60 engines, the final and strongest generation of the pre-emissions DDEC IV platform. These Premium engines featured upgraded internals and improved calibration strategies designed for higher performance and longer service life straight from the factory.

Because of that, the stock 7650's injectors make an excellent performance upgrade for any standard Detroit 12.7L Series 60. Unlike older designs, these come configured with a 9-hole spray pattern instead of the traditional 8-hole layout—delivering cleaner atomization, more efficient combustion, and noticeably better throttle response.

Pair these with a solid turbo upgrade, manifold, and tune, and your old Detroit will stop living in the right lane—you’ll have a left-lane hot rod with the manners to pull hard and the reliability to do it every day.

Why Momentum Worx 7650's Injectors Are Better

Momentum Worx supplies GENUINE Bosch Reman 7650's injectors—rebuilt under the same strict OEM specifications as brand-new units.
These are not the old-school parts-counter “rebuilt” injectors with questionable parts and mystery setup.

Bosch Reman means:

• OEM-correct internals

• Proper flow calibration

• Precise pop pressures

• OE spray pattern verification

• Real durability and long life

You’re not just buying an injector that “gets you down the road.”
You’re buying one that gets you down the road faster, cleaner, and far more efficiently.
