Got some updates on the spark plug tube. I just picked up one and dropped it off at my partners shop. Hes gonna discuss it with his machinist and see what we can get done.
Aluminum 6061 seems like the material we will be using though. I'll have the parts drawn up by tomorrow, and ill run some tests on it to make sure we wont run into any issues like thermal expansion etc.
We are guessing that porsche chose to make the tubes out of plastic because its cheap and also acts as a heat shield to protect the coils. Our solution will be to try adding a thermal coating to the tubes.
The final issue is the O rings. the OEM o-ring looks like its very high quality, that said it still seems a bit expensive for what it is, we will try to source a cheaper one with the same quality and include it in the kit.
Either way, i'll post more info as i get it.
Thanks again for the feed back
