The Deatschwerks WRX / STi Fuel Injectors includes a set of 4 100% drop-in fitment injectors for Subaru WRX 2002-2011 and STi 2007-2011. 

The new WRX injectors have been developed with the same commitment to quality, drop-in fitment, and easy tunability that have made the Deatschwerks Subaru injectors the #1 choice of top Subaru tuners around the US and world. 

High impedance coils for compatibility with OEM injector driver, ethanol and methanol compatible, each set is flow matched to within 1-2%. A flow report is included with your specific flow results, drop-in fitment for easy installation. Price listed is for a matched/balanced set of 4 injectors. 

Deatschwerks fuel injectors are built from using only OEM Cores. Some of these injectors are new and some of them are core swaps. Each injector that is processed and built by Deatschwerks goes through a 40 point data inspection before it can ship out the door. 

DeatschWerks has a core buyback program available for certain fuel injectors. If this buyback program is available for your application, information will be included with your injectors.
