Customers like the performance, throttle response, and ease of installation of the spark plugs. They mention they work great, have a smoother idle, and noticeably better acceleration. Some also like the ease of idling. However, some customers have reported misfires and the plugs don't fit properly. Opinions are mixed on the quality.
