100% Over Injector for High-Performance Builds

If you’re chasing serious power gains from your 2.8L Duramax, the Exergy 100% Over Injector is the kind of upgrade that makes a noticeable difference. Built from the ground up as a brand-new unit—not a reman—this injector doubles the fuel delivery compared to stock, making it a perfect match for high-performance builds that demand more out of every component. Whether you’re pushing for peak horsepower or running a larger turbo setup, this injector ensures you’ve got the fuel to back it up. Exergy doesn’t cut corners. Every injector is precisely calibrated and flow-matched to within 1% for consistent performance across the board. That means smoother power delivery, cleaner combustion, and better throttle response under load. These injectors aren’t just about flow—they’re engineered for reliability too, built using OE-style construction and tested to meet strict quality standards.

Designed for Tuned Applications

Keep in mind, this level of injector does require custom tuning to take full advantage of the added fueling. But for performance-focused owners who want reliable, repeatable results, Exergy’s 100% Over Injector is a no-brainer. It fits like stock, performs like a race part, and helps unlock the full potential of your Colorado or Canyon’s 2.8L Duramax.
