    So in the process of getting ready for my engine build, I managed to score a set of stock injectors for $100. Of course I wanted to go and get the flow tested and cleaned, but to do that I of course needed a seal rebuild kit, but Mazda's OEM kit is DUMB expensive, and I had a better idea.

    @JohnnyTightlips and a few suggestions I have seen on Facebook led me to these Rock Auto rebuild kits. For about $8 a kit, I got 4 kits (1 per injector) shipped to my house for about $37. An absolute steal compared to the OEM ones.

    Install was just a TOUCH tricky. The plastic ring that sits directly under the blue O-ring does NOT have a 'cut' in it like the OEM one does. You will have to force it on a little bit and get it over that top piece of the injector. I put it kinda diagonally on the top and forced it with my palm and it went on. OEM seal with the 'Cut" pictured here.

    Besides that little quirk, the rest of the seal components go on fine and I can't really tell the difference from OEM. That cut, and the color/material of the very top plastic seal, and the color/material of the nozzle seal are the only things I can see that is different. Nozzle seal pictured below.

    (note if/when installing this nozzle seal, the beveled side goes AWAY from the tip. There is a picture on Jim Ellis parts that shows that)

    Besides that stuff, it looks fine. I will be sending these out to Injector RX to get them cleaned/flow tested and I will report back if they seal/don't seal when being tested. If everything goes okay, I will throw them in the engine when I get it with upgraded injector seals and see if they can hold up to some real power. Here are a few extra pictures.

    Look forward to the results. I’m sitting on a set that I need to send to RX.

    Confirmed with Injector RX that all seals need to be included when sent to them. Screenshot attached.

    Good to know.

    Thank you for posting, I would've sent them all bare bones.
