The TR55GP is a standard temperature platinum plug, essentially a stock alternative to delcos. I use NGK plugs and K&N Filters on all of my bikes so I simply went the same direction on my GP. Have to admit once I ditched the stocker stuff for what I have, I clearly have more power on demand and when I punch it over 3k on the tach and keep going I can tell it’s breathing much better and firing more smoothly. Really simple stuff made pretty noticeable differences.
