Anybody used them or know anything about them?
Thanks gents.

Not a lot of information but, for what it's worth, I had them put in my RX-8 when I had the RENESIS engine rebuilt and bridgeported by Aston at Essex Rotary about 2.5 years ago. Engine still going strong 12k miles, and 12 trackdays later.

Was told advantages were that they are more durable and less prone to shattering. Plenty of other RX-8 guys had used them and had no issues. Spoke to a few knowledgeable people and decided to use them.

Thanks for that Malcolm, Ive only read good things about them, price is good to.
Great to hear from someone actually using them, thanks so much for the info
