The Fuel You Need for Serious Competition

If you're tuning your 2004.5 to 2005 Duramax LLY for more than just everyday driving, the Industrial Injection 0986435504-R2 30% Over Injector is a key upgrade worth considering. Designed specifically for high-performance race and sled pull builds, this injector pushes 30 percent more fuel than stock, flowing at 27 liters per minute. That extra volume gives your engine the fuel it needs to support aggressive tuning, increased boost, and higher RPMs. It’s the kind of upgrade that helps transform a strong truck into a track-ready performer, giving you a noticeable edge when throttle response and power delivery matter most.

Purpose Built Sold One at a Time

This injector is sold individually, so if you're building a full set, make sure to grab eight. Every unit is carefully built to handle the demands of competition-level driving, while maintaining consistent flow and reliable performance under load. A refundable core charge applies, as long as your returned core is in usable condition. Whether you're chasing your best time at the strip or pulling through deep dirt under a full load, these injectors give your Duramax the fueling it needs to back up your tuning and hardware upgrades. They're built to perform under pressure and give you confidence with every pass.
