Premium Fuel Injector Upgrade by Exergy

If you’ve outgrown your stock fuel system but still want to keep your L5P Duramax streetable and reliable, the Exergy E02-10708 New 60% Over Injector is a perfect middle ground. Built specifically for 2017–2019 Silverado and Sierra HD trucks, this injector gives you a serious bump in fuel capacity—60% over stock—without sacrificing clean idle, smooth throttle response, or everyday drivability. It’s ideal for truck owners running upgraded turbos, tuning, or fuel system mods who need more fuel to support added power, but aren’t looking to step into race-only territory. What makes this injector stand out is the attention to detail throughout the build. The nozzle is precision-enlarged using abrasive flow honing, a process that reshapes the internal passageways without damaging the injector body or compromising spray pattern. That means fuel atomization stays tight, helping with both combustion quality and EGT control. Each nozzle is flow matched within 1% to ensure every injector in the set delivers identical fuel volume—no uneven cylinder fueling, no surging, no guesswork.

High-Quality Construction

Exergy takes quality seriously, running every injector through four separate quality control stages before assembly, then testing each unit across multiple calibration points on specialized, in-house equipment. When the set ships out, it includes a detailed calibration sheet so you know exactly what’s going into your truck. This isn’t just a performance upgrade—it’s a carefully engineered component that gives you room to grow your build while keeping the engine responsive and manageable. Of course, with this level of fuel delivery, proper tuning is required to keep EGTs in check and get the most out of the added flow.
