2007.5-2010 GM 6.6L Duramax 2500HD/3500HD Industrial Race 4 50% Over Injector 0986435520-R4

The Factory OEM stock and performance Injectors start out as a genuine stock OEM injector body then have been modified in house with BRAND NEW Factory OEM parts including the nozzles. We then extrude hone and balance them to a perfect matching set injectors that flow 50% over. These injectors work great in a completely stock all the way up to a full built competition truck. We typically see a 1-3MPG increase in fuel economy. We balance the injectors to a tighter tolerance than the original manufacturer and have put a lot of time into making these the best injectors money can buy.

These injectors come with a new copper crush washer and o-rings for installation. Injectors are an OEM Genuine part that is a direct replacement injector. Each injector is Individually tested on a state of the art test stand to ensure that they meet OEM specifications. Each test includes a resistance test, system leak test, purge, idle speed test, mid load test, full load test, and static back leak test. Each test cycle checks solenoid response time, back leak flow, and fuel delivery.

Each injector has a $100 core charge and is fully refundable if they are shipped back within 30 days.

All Industrial Injection products are covered by a one year/unlimited mile warranty.
