30% Over Injector for GM 6.6L Duramax

If you're ready to wake up your L5P Duramax without going overboard, the Exergy New 30% Over Injector is one of the best ways to do it. This isn’t just about throwing more fuel at the engine—it’s about precise gains in power, throttle response, and drivability while maintaining the reliability you'd expect from a daily-driven or tow-ready truck. These injectors are ideal for owners running mild performance upgrades like tuning, exhaust, or a drop-in turbo, and want a clean, controlled increase in fueling to match. Each injector flows 30% over stock, giving you the extra capacity you need for more horsepower while still being completely streetable. Whether you’re hauling heavy, chasing a quicker spool, or just want a little more fun under your right foot, this upgrade offers real-world performance you’ll notice immediately. Exergy doesn’t cut corners, either—these injectors are flow matched within 1% using specialized in-house equipment and are backed by a level of testing and calibration most companies simply don’t offer.

High-Quality Construction & Design

The enlarged nozzles are honed using abrasive flow technology, ensuring consistent flow and proper atomization. That means smooth combustion, clean idle, and great throttle control—without the smoke and surging you get from poorly matched injectors. Each set goes through four separate quality control checks during the build process and is shipped with a detailed calibration sheet, so you know exactly what you're putting in your engine. A seal kit is also included, with fresh copper washers and O-rings to make installation as seamless as possible. And while these injectors work great with a near-stock setup, proper tuning is recommended to unlock their full potential and ensure optimal drivability.
