Which do you guys think I should go for?
I want to use NGK Iridiums, they are in the car at the moment and work very well, I did have a problem elsewhere and coked the engine slightly meaning I only just failed the mot emmissions.
Before I was using the 6 heat range as the 5 heat range was not previously available.
However now it is.
The standard on my car is the 5 heat range. However the compression is raised so I "should be" using the 6 range right?
What do you guys think?
