Could I please get some help here. Any information would be appreciated. Has anyone tried Splitfire platinum spark plugs? Are they any good or are their products just hot air? Surely some must know something about them. Is platinum better than copper?

 

Platinum is far better than copper. Longer life, less loss of spark strength over time. As far as SplitFire, I don't know. A lot of people run NGK's which are the OE plugs, in case you didn't know. Jan has been using Brisk plugs (it is Brisk, right? ) Maybe we'll get lucky and he can fill us in on his choices for R50 plugs. I'm thinking of doing mine again, soon.

 

Say no to spilt fire. The Brisk LGS work well in the GTO and I have a set coming from Jan for the Mini.

Copper for performance but don't last long, then Iridium and Iridium.
Silver is the best.
