Deatschwerks Subaru STI (04-06) Side Feed Fuel Injectors

All Deatschwerks high flow fuel injectors are built using only quality OEM cores. In addition, each set is balanced to within a 2% flow variation. For our customers, this means better fitment, easier tuning and increased reliability. All injectors are backed with a comprehensive 12-month warranty. Most aftermarket injectors go straight from the production line to the shipping department. At Deatschwerks, we have added what we consider a crucial step of flow balancing and quality assurance testing on EVERY set of injectors we produce - not just one or two from each lot. Over 40 data points are collected and analyzed on each injector to be sure our customers only receive the best end product. All of our testing is performed in-house on our custom built New Age Technologies injector flow bench.

Deatschwerks injectors are DIRECT FACTORY REPLACEMENTS for their listed applications

Deatschwerks 2004-2006 STI side feed injectors are available in flow rates from 550 to 850cc and utilize an OEM 12-orifice atomization plate (except for 550s and 650s which use a 4-hole version).

Please note that these are for 2004-2006 STI models only; 02-07 WRXs & 2007 STIs use top-feed injectors.

Notes: 2004-2006 STI only Injectors are sold in sets of four (4) and require ECU tuning.
