It’s a no brainer
I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.
