Plug Gap for modified micra

[Paul Smith]

Hi,

I have now bought the NGK BCP7ES plugs because the equivalent bosch super 4's are pants and keep stuttering. I know the manual gives standard plug sizes from 0.8 to 1.1?

What size gap would be better for a modified micra?

thanks

Ahh yes you found the super 4s are rubbish too..

Gap them to 0.9 it will be fine.

Don't know why the super 4's weren't good. They have been good in all my standard cars in the past but couldn't hack it this time unfortunately
