- It is YOUR responsibility to be aware of your local laws regarding vehicle modifications. Therefore these injectors are sold for off road use ONLY (racing, pull truck events, etc)

- Please note that Performance injectors are build to order - please allow a few extra days for delivery


50 HP :

Our most popular injector. These injectors are a 'mild performance' upgrade - great for a daily driver or for towing purposes. The 50HP injector is very popular because no other modifications are required - install and drive!

Nozzle flow is 30% over stock - the industry considers this a 50HP nozzle and this has proven realistic in real world experience. Results can vary depending on tune and condition, and other modifications. Your power (and mileage) may vary up or down!

100 HP:

For the more serious performance enthusiast, these injectors flow 45% over stock.


We also offer 60% over and 100% over injectors for very serious performance builds. Custom sizes may be available also. High flow injectors may require additional fuel system modifications, such as increased lift pump capacity, and stroker or dual CP3 pumps. Please do your research carefully before purchasing extreme high-flow injectors.

Please note that Duramax performance injectors will ship to exact match credit card billing address or Paypal address only. Non-compliant orders will be cancelled.
