Description
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.

I installed these at the same time with my DW 65c pump. I have an 08' STi and have tuned on a dynojet dyno at 344whp and 418wtq on stock VF48 turbo. The highest I've seen my Injector duty cycles go is 86% for reference... Been about a month so far and they are doing great!

  • Q: e85  subaru 7 months ago

    Answer

    Can I run e85 with theses fuel injectors or do I need a bigger size?


    • A: These injectors are compatible with E-85 fuel and the size of your injector will be dependent on your modifications and tune.

    • A: Injectors will require a new tune. The 18g is a larger turbocharger and will net you more power over the 16g.

  • Q: Downgrading  jamezcua3460751 9 months ago

    Answer

    Hi i currently have a tune set for 870cc modified stock injectors. If i buy these to get a closer flow rate between all injectors would i need a re tune right away or would i be able to get away with just swaping for about a week before the retune? Or would detchworks recommend even flow testing the injectors i have now


    • A: These would require a tune immediately after installation to run properly.
