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.

Great! Fuel economy average will be inaccurate though.

Fantastic injectors. There is a very nice data sheet that comes with them to show you latencies and flow rates that these injectors tested at. I just threw the numbers in the tune and the car fired right up. I was amazed. I ended up scaling these at 790cc in the ecu. A bit of tuning is still needed to get them perfect. Tip in fueling needed to be added to and a bit of maf scaling will take care of the rest. Be aware that if you have a 08+, changing out your stock injectors will make your l/100km or MPG display on your dash inaccurate. There is no way to fix this. I was a bit disappointed about that. Other than that they are great!


  • AnswerQ: injectors  wrxloki09 1 year ago

    will these injectors work fine without overworking them with a td05 20g or 18g on a ej205 motor with sti intercooler and dw200 fuel pump? and stock solenoid

    • A: As long as you are using pump gas these should be enough, but I do recommend going with the EV14 1000cc if you are looking to run E85.

  • AnswerQ: 2015 WRX  drewpee432120343 2 years ago

    Will these fit a 2015 WRX?

    • A: These are confirmed to fit the 2015 STI but the 2015 WRX has an entirely different injector setup.

  • AnswerQ: will car run on cobb stage 2  2012booSTIng 2 years ago

    I have these injectors and dw65c fuel pump for my 2012 sti will the car run on cobb stage 2 tune. I would be installing then driving to get a pro tune immediately.

    • A: We do not recommend using larger than stock injectors with the Stage 2 map because those maps are designed for stock injectors. It would be best to get a base map from your tuner for larger injectors before running the car at all.

  • AnswerQ: spacer needed?  Subiesuperlover 2 years ago

    Do I need to put in spacers to connect the stock fuel rail to these injectors?

    • A: Spacers for the fuel rail are not required. These are drop-in fitment.

  • AnswerQ: wheel hp supported  ac262088701 4 years ago

    I am shooting for 350 whp w/ a blouch 20g xt turbo. will these support that horse power? or is 850 a better choice?

    • A: It really depends on the fuel your going to be running. I personally would run the 850cc's on pump gas. I also recommend consulting your tuner and getting his/her opinion. Thanks!
