Unlock The Full Potential Of Your Duramax

If you're building serious power and your stock injectors just aren't cutting it, the Exergy E02-10518 200% Over Injector is what you need to get your 6.6L LML Duramax breathing fire. These are not basic reman injectors or off-the-shelf upgrades. This is a purpose-built, high-flow solution designed for trucks running big turbos, upgraded fuel systems, and aggressive tuning. The 200% over fuel output means you're delivering massive fuel volume to support extreme horsepower gains, whether you're drag racing, sled pulling, or pushing limits on the dyno. Exergy builds these injectors with true OE-level precision and tests each one using some of the most advanced fuel system equipment in the industry. That means every set is built to perform, not just on paper, but under real-world load, at idle, and at wide-open throttle. What’s more, these injectors are fully mapped and verified for shot-to-shot consistency and timing accuracy, so you’re not just throwing fuel blindly. If your build demands more than average, these injectors are built to keep up.

Engineered With Real OE Precision From Start To Finish

The Exergy 200% Over Injector isn’t just a bigger nozzle, it's a fully re-engineered component built with insight straight from the OE development world. Unlike many aftermarket options, Exergy uses Bosch factory-level equipment to verify not only total fuel output, but also shot-to-shot consistency and precise injection timing. Their testing process goes beyond standard flow bench methods, using calibration points that cover idle through full-load operation, along with custom testing tailored to the high-performance diesel market. This makes these injectors especially valuable for custom-tuned trucks running EFI Live or standalone ECUs, where detailed fuel control is critical. Designed specifically for the 2011-2016 Silverado and Sierra 2500HD and 3500HD trucks with the LML Duramax, they drop in with proper supporting mods and work seamlessly with high-horsepower builds. Backed by former Bosch engineers and OE-grade equipment, every injector is built to perform reliably under the most demanding conditions. This is precision fuel delivery that doesn’t just meet expectations, it raises the bar entirely.
