What spark plugs to go for?

Post by Floydian » Thu Feb 01, 2018 5:19 pm

Hi,

I’ve read that it is a good practice to go for colder spark plugs with tuning.

Factory wise my car is fitted with Beru Z332 plugs and currently use NGK 95770 (which are used in Mini JCWs etc.) - 95770s are same Beru’s in terms of heat range.

Should I stick with NGK 95770s or move to NGK 97506s which are 1 step colder?

Aside from being one step colder 97506s have a centre electrode size of 1.0mm instead of 0.6mm in the 95770s. What difference will this make?

Thanks
