    I have a Blouch 16G-XT turbo and needed to upgrade injectors. My tuner recommended these for my 2004 STi. We're still working on the tune but so far, they work well. Installation went fairly easy, just have to get some of the power steering lines out of the way on the passenger side.

    Great injectors and great customer service 2 years ago
    5out of 5stars

    These injectors are great, were more than enough for my stage 2 lgt. Gives you lots of room to work with safely. Had one faulty injector but the guys here at rallysportdirect helped me out no problem with setting me up with dw to claim another one. Can't beat a 3 yr warranty.
