The side-feed injectors in the '04 F-XT (yellow cap) are 100% identical to the yellow cap side-feeds in the '04 STi. They are the same part number.There is a lot of debate on what size the sidefeeds actually are in the 04-05 fxt's. They are at least 500's and depending on fuel pressure can surely run over 550cc.
Version6 side-feed injectors are a different style from the side-feed injectors in the USDM F-XT and STi. Sorry to burst your bubble.Hey,
I'm just after some info on upgrading my 440cc side feed injectors on my V6 Wrx motor. I was after a direct replacement.
Does any of the foresters come out with 550cc side feed injectors to suit my wrx motor?
