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.

The EIX range of plugs are garbage and not to be used on rotaries, NGK do not recommend you run them period on rotary engines here in Australia as far too many have failed.

B*EGV's by comparison can withstand melting of the porcelin without a cracking failure and the centre electrodes dont fall out due to different construction method

interesting. All the racing plugs that racingbeat sells are all eix's except the 11.5 racing plug (39 dollar a piece)......all of witch you have said not to run on a rotary. One more reason why you are so controversial on this site, lol. Not saying anything about you just saying DAMN! what the **** 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
