Deatschwerks Subaru WRX & STI top-feed & side-feed fuel injectors are engineered to fit your OEM harness, fuel rail and manifold and are built using only quality OEM cores. Each set of Deatschwerks WRX & STI injectors is balanced within 2% variation, making them easy to tune. This means better fitment, easier tuning, and increased reliability. Deatschwerks injectors are backed by a comprehensive 12-month warranty.

Top Feed Injectors

Deatschwerks Subaru 02-07 WRX & 2007 STI top-feed injectors are available in flow rates from 565 to 1000cc and utilize an OEM 12-orifice atomization plate (except for 565s and 650s which use a 4-hole version). They are available in standard, or "Cobb Spec" sets of 4.

Deatschwerks Cobb-Spec 565cc, 650cc, and 750cc injectors are designed for use with off-the-shelf Cobb Accessport Maps. Slight coil and flow parameters have been set to optimize these injectors specifically to Cobb's Accessport maps. These are really only a necessity if you are using a Cobb map for the Accessport and are not having your WRX or STI Pro-Tuned.
