What spark plugs are people using ?

Hi

The standard plug for a 240 is the BP6ES but I read somewhere that when you start using unleaded fuel you should go with a hotter plug so I have been running BP5ES.

 

What are others using and do you notice any difference or more or less plug fouling ?

It depends to some degree on the amont of usage. If infrequent use, the BP5 is a better plug to use.

take my advise go the hotter plug unless you like cleaning them every month or two also the bosch super 4 plugs seem to be a bit better then the ngk dont foul up as easy

This is the expensive way to go but I run BP6 iridium plugs.  If I run normal plugs then I need a new set pretty much every race meeting.  The iridium plugs last me at least a year and I've found the engine to be a little more responsive off boost.

BP7ES here.

 

I've fouled a couple of sets with a less-than-ideal tune, but once tuned properly, go just fine.
