These spark plugs have lived up to their reputation, providing consistent ignition and improved performance for my ride. The automotive-grade construction is a major plus ensuring long-lasting durability and reliable operation. The only downside is the slightly higher cost compared to other spark plugs on the market .Overall, I highly recommend these spark plugs for any automotive enthusiast looking to improve their motorcycles performance..
