Plugs were perfectly packaged for overseas shipping. Arrived in expected time frame. Price was better than expected. Great company to deal with as they supplied timely ongoing updates of processes right up to delivery. Many thanks 👍

I installed these in my 2021 Indian Scout Bobber ABS. I can see the improvement over the regular plugs. The bike starts better and runs better at idle and full throttle. I recommend them.
