RE: Brisk Spark plug alternative for MVVS/Evolution?
* Champion RDJ7J or RDJ8J; or
* NGK BMR6F
Choice is yours. Tip will need to be removed, it is slightly easier to do the NGK plug as it has a removable (screw on) HT fastener.
Do a search in this forum on this subject, it has been raised a few times.
Best of luck
