Built to deliver 24 liters per minute, this injector provides a noticeable increase in fuel volume over stock while maintaining drivability for performance street builds or light competition use. It’s a great choice for trucks that tow heavy, run mild tuning, or occasionally hit the track or sled pull event. By providing that extra fuel your engine needs under load, this injector helps you unlock more horsepower and torque without overwhelming your setup or daily driving habits.

Quality Remanufactured Performance With Practical Value

Industrial Injection’s remanufacturing process ensures that every injector meets high standards for reliability and consistency. Whether you’re replacing a worn unit or upgrading your entire set, this injector is sold individually to give you complete control over your build. The refundable core charge adds extra value when you return a rebuildable injector, making this a smart investment for anyone looking to increase performance without overspending. If you’re chasing more power but still want to keep your truck practical and reliable, this 20% over injector is built to help you get there with confidence.
