Any can be used with...anything with a belt. The IR units must have a port drilled in directly over the belt in the cover...which is the most accurate way to measure belt temperatures. The air temp type can have their sensors just stick through the exhaust boot into the air flow. I use the Trailtech air temp type. It's all I need to keep my belt from being a problem. If I had a performance machine with 100+ HP,...I would probably want..or need an IR type.
