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.

Everyone thinks these injectors aren't good on forums and other places and I have heard these are hard to tune. I have had no problems whatsoever with these, no negative comments from my tuner when I had him tune my setup with these. They were fairly accurate except for one which was slightly off on the flow test but they were still within spec and I have had no issues and they work really well. I'd buy them again.


  • AnswerQ: 08 sti with 20g turbo  smjfifa02009 3 months ago

    Hi can this 650cc injectors support a 20g turbo? Or at least has to be 750cc?

    • A: These would be a bit small for a 20g turbocharger, 850cc would be the safe option.

  • AnswerQ: 2013 stage 2 wrx  antoniojb552662 1 year ago

    would these be good with a stage 2 set up? would I need a new tune and rule pump?

    • A: This would require a new tune, and fuel pump recommended.

  • AnswerQ: 2003 wrx with vf39 with 650cc and stock fuel pump  japan4ej20sti38344 2 years ago

    got a 03 wrx and was wondering if the stock fuel pump would keep up with the 565 or 650 injectors running a vf39?

    • A: The DW200 fuel pump would be plenty for these injectors if you are using pump gas.

  • AnswerQ: Proper upgrade  wangdilee22322 2 years ago

    03 WRX. would these injectors run fine with TD05-16gxt7cm^ and a 255 pump? stock TMIC and a full turbo back?

    • A: Yes if tuned properly these injectors should not have a problem with the 16g from Blouch.

  • AnswerQ: Not sure of the size  Subaru man 3 years ago

    im a little confuse about what size I should go with in my 02 wrx, I do have a vf39 in it and my injectors are not stock but I don't know what size they are but I can tell you they are blue, I got the car with them already in it. My car is at a stage 3 rite now but if I was to change my injectors should I go with the 565cc or the 650cc

    • A: If you already have upgraded injectors you will want to take out the ones you have and get them tested. No point in getting the same injector that you might already have. As for the size injector for your turbo, the VF39 will be fine with a 565CC
