The Industrial Injection 40% over Race 3 Injectors start out as a genuine stock remanufactured injector from the factory then have been extrude honed and balanced to a perfect matching set injectors that flow 27LPM. The Race 3 40% over injectors should be ran with one of our Phatshaft turbos or our compound turbo setups to run more efficiently and to help reduce EGTs. We Also recommend a CP3 upgrade like our 85% over Dragon Fire Pump or Dual CP3 Kit. We typically see a 1-3MPG increase in fuel economy. This is a 100% OEM Reman Injector directly from the factory themselves simply sold and modified by us here at Industrial Injection.

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.
