    I got a set of used OEM fuel injectors from a parts car (04 WRX). I'm thinking about decapping them. Those who did it before, did you have to go get them clean and other stuff afterwards or are they ready to install with new o-rings, gask and tune without any other requirements? TIA

    From my understanding of it, which is limited, you should have them cleaned and flow tested.

    Unless you were really pushing the limits of the existing injectors i would just have them drilled, cleaned and flow checked. I did this with my itb converted spectra5 because there was literally no kia/hyundai aftermarket support at the time

    You're going to need to explain yourself on that one.

    it sounded awesome, still not terribly fast but back to the original topic I had to get some injector caps drilled slightly larger, cleaned and flow tested to make that setup work. I caution though that the cost of doing that might exceed buying upgraded used injectors from FB market, craigslist, etc.

    I did mine in a college CNC lab so it was technically free :D
