Here at Brewed Motors precision matched fuel injectors are a key ingredient in all of our Subi EJ20 and EJ25 builds. Everything from street cars making 400whp and getting 30+ mpg to full blown drag cars running staged fuel injection systems the ID injectors are Brewed Motors 1st recomendation for any Subaru build looking to make big power. With special internals designed for Alcohol (Ethanol/Methanol) based fuels the ID1300's are the a true "Flex Fuel" friendly injector that will perform perfectly for years to come. If you love love crazy Subaru builds check out the EJ powered V-mount "Driftaru" (this car now runs a 2jz) Full-Race twin scroll GTX3076R Subaru WRX STi with ID2000cc.

The 1300.48.11.WRX.4 injector kit includes 4 ID 1300cc injectors that are a perfect OEM fit for the factory fuel rail or aftermarket rail using a 11mm top Oring seal. Kits ship with everything you need to install: flow matched injectors, data sheet for tuning and plug n pin connectors. If you want Plug and Play connectors just give us a call or send an email to get the absolute best pricing for a complete "Plug and Play" kit. For builds looking to make over 500hp we highly recommend using an aftermaket fuel rail. The stock EJ fuel rail has less than ideal inlet/outlet positions that will prevent even fuel flow between all the injectors on high power builds. Package deals on fuel rails and Injectors available at huge savings, contact us for details and options.

  • High Impedance, no need for injector drivers or injector resistors
  • The high pressure and excellent atomization makes these are great option for high power N/A applications as well.
  • High duty cycle, with a recovery time of only 1ms, all injectors will run up to 92.5% duty cycle at 9k rpm and 95% duty cycle at 6k rpm while maintaining linearity within 1%
  • Excellent low pulse width response, linearity within 2% all the way down to 2ms, predictable response down to 1.5ms. Using a 3 dimensional battery comp table with Motec V3 software, low pulse width response can be linearized to practically zero flow.
  • Excellent consistency, no sets will require more than a 1% trim
  • Ruler flat response, unmatched linearity means easy tuning and accurate compensations.
