Busa Spark plugs

[Jackard]

Hi,

Which kind of spark plug do you use on Hayabusa engines?

For the moment i've NGK CR9EB, RPE tell me to use NGK CR9E.
Does anyone know the differences between those 2 ref?

[Josh Smith]

the cr9eb just has a fixed cap on the top I believe, whereas the cr9e has a screw cap on top

Like Josh says.

Use the EBs if you've still got the floppy 'pontefract cake' leads - there's enough scope for loss of contact with those without worrying about whether one of the spark plug tops has vibrated loose.

When I changed mine recently I put Iridiums in. Interestingly, cold starting is now noticeably easier.
