Certainly make a difference up top. Few more mods and a tune should get the potential out of these upgraded plugs. Smoother idol on cold start.
Idols smoother but absolutely no performance gain at all with the MSD coils as well
Currently using just a box tune on proceed, these plugs made a huge difference, every gear feels like it had a bit more power when I'm pushing it. Was definitely worth the upgrade
Have installed these with the MSD ignition packs, and what a change! Feels smoother and much happier through the rev range!
