Hey all- My C34 RS Stag is dual-fuel, and has an evaporative gas injection system on it. I do a lot of kays every week, and it runs the majority of time of gas because the $ savings are huge.
Only problem is I never really get very much life out of the plugs- probably not even 10k kms before they start missing at light load/moderate throttle acceleration. Does anyone know if there's a special type of plug that works well with gas, or what sort of heat range and gap I should be running?. I've tried a few different variations now, and even iridiums were dead in less than 20,000- not especially good value at $180 a set.
Engine is pretty much standard and only runs 7-8 psi, and the car has a healthy set of Splitfire coils.
Changing them so often is a tedious job on an RB25. Any insight will be great.
