IE2400 - Bosch 2400cc Injectors for Subaru EJ20 & EJ25
 
The largest injector we offer for the EJ20/EJ25 platform exists for one reason: headroom.
 
The Ichiban Engineering IE2400 is the top of our Subaru injector lineup - Bosch-based, built for setups where fueling margin matters as much as raw flow, whether that's E85 tuning stability, a methanol blend, or simply not wanting to be at 95% duty cycle on your daily.
 
Every set is flow matched, static and dynamic, on our ASNU system to a strict 2% tolerance, with a flow data sheet included with every order.
 
Top hats are CNC machined from billet aluminum to our own spec.
