IE1300 - Bosch 1300cc Injectors for Subaru EJ20 & EJ25
 
More boost, more fuel demand, more reason the 1000cc set won't cut it anymore.
 
The Ichiban Engineering IE1300 is built for the Subaru EJ20 or EJ25 that's moved past entry-level bolt-ons - Bosch-based, rated to 600whp on E85, with the same flow-matching rigor as every injector we sell.
 
Each set is tested static and dynamic on our ASNU system to a 2% tolerance between injectors, with a flow data sheet included so your tuner works from real numbers instead of assumptions.
 
Top hats are CNC machined from billet aluminum to our own spec - no generic hardware forced into a fitment it wasn't built for.
