^^^^ you make an awesome point on loop glows.....my car had upgraded plugs when I got it so I didn't do the mod.....unfortunately they cut the ground strap but I love the idea that you know right away if your plugs are good or not.....if one breaks, you know it needs replacing....where as a pencil upgrade with not show its self unless removed and tested.....if I ever need new plugs I may contemplating going back to loop and keep a spare or two in the glove box.....quirky features are the best part of these cars....I love my evil servo system because of that....
