On two occasions while doing numerous highway pulls I had my knock sensor go nuts with very high knock levels and after checking everything on the motor....one leading BR9EIX plug was the culprit, half of the porcelain insulator tip was gone !!!!!!
2nd time I went straight to the plugs and same deal. This time the motor had a slight drop in vacuum possibly from scratches but a year later it still runs strong.
With the BUR9EQs all around I never had this happen.

One more reason why you are so controversial on this site, lol. Not saying anything about you just saying DAMN! what the fuck do I believe. Racingbeat who have been around for years and years or a guy on a forum............. Same goes for your water injection. I don't really like racingbeat all that much anyways, lol.

I personlay have seen EIX's electodes fall out and also porcelin shatter on the same engine that runs perfectly on EGV's. no tuning issues or anything else. I dont recommend the plugs at all ....... they are not durable enough for a rotary engine application.

The other type of failure they suffer is bent centre electrodes as well (just before they fall out!)

Meh me contorversial NO never :)
