Perfect for karting!
Worked well - bought these in bulk for a kart racing weekend. I change them out twice during the weekend of hard racing because I do not want to be that parent that can't get their kid's kart started when it's go time!

Awesome plugs for the price.
These are like brisk plugs but a quarter of the cost great upgrade for plugs as long as you know your heat range.
