RX8 injectors - what seals?

I have an S5 engine in my FB and I used yellow RX8 injectors for both primaries and secondaries. After about 2000 miles, the injector seals look shot, and I smell gas in the engine bay under heavy throttle.

Did I use the wrong seals (all rx8 seals I think)? Or did I just use poor quality gaskets?

I am not sure what replacement parts to order so it doesn't happen again. If anyone else is running RX8 injectors successfully I'd love to know what parts work. I found a post specifying a combination of RX8 and RX7 injector seals but didn't specify which RX8 seals

I might just have to buy a few different ones from Mazda and see what works...
