CAT C15 ACERT 625HP Injectors – 10R3261

The 10R3261 is for the 625HP Caterpillar C15 ACERT — the big dog factory rating. 

Fitment for BXS, MXS, NXS.  NOT SDP

If you’re running one of these engines, you already know it’s not built to idle around parking lots. It’s built to pull.

When injectors start getting lazy on a 625 ACERT, you feel it immediately:

• Soft throttle response
• Excess smoke under load
• Uneven power delivery
• Fuel economy slipping
• Random contribution / balance faults

These injectors restore the crisp fuel delivery the ACERT platform demands — clean atomization, proper timing events, and strong pull when the charger lights.

Built for 625HP ACERT Calibrations

The 10R3261 is engineered to support factory 625 horsepower C15 ACERT engines where fueling volume and precision matter. This isn’t a “close enough” part number. It’s the correct injector for high-output on-highway ACERT applications.

Bolt them in. Set the overhead. Go to work.
