ALL INJECTORS SOLD! SOLD! SOLD!!!

cleaning out our garage and got two sets of these I just dug up, came off a couple of STI long block tear downs from a couple 04-05 longblocks at our shop and have been sitting around for the last couple years so probably only 2-3 years tops on these so basically damn near new. All O-ring are in great shape and ready to drop in.

Sell each set for $150 shipped! Or if your in the SF bay area can meet up any time :)

are they true sti? cause teh regular wrx had yellow top injectors as well. And everything ive researched says 02-05 sti ran a 485cc injector. Got any flow charts to prove they are 500cc's?

all the 02-05 WRXs had top feed injectors, these are STI side feed. there were no 02-03 STIs in america so the ones you found on google were probably JDMs, those did come in top feeds. but any sidefeeds you find in the US and going to be the STIs (yellow 550cc)

Ive heard that too, it also depends on what PSI you are testing them at. in any case theres plenty of guys on NASIOC pushing over 320+whp on stock sti injectors, and thats with more driveline loses with AWHP too on low reading mustang dynos, so these should be able to support 350rwhp +/-, if you're looking for more than that the nismo 720s are probably your best bet.

FIRST SET SOLD TO OBSOLETE! ONE SET LEFT!!
