Are Halo Spark Plugs available for motorcycles, snowmobiles, ATVs and marine engines?
Yes. We do carry Halo Spark Plugs for these applications, however, at this time we only manufacture 14 mm plugs. Some of these vehicles use 10 mm to 12 mm plugs. If your vehicle uses 14 mm plugs (check your owners manual if you’re not sure) and you would like to order, please contact us for more information. We will be glad to assist you.
