purchased to replace an unreliable westach gauge. This is a much higher quality instrument for just an little more $. Be advised that if you need a spark plug gasket type cht sender, unfortunately the folks at the order desk are just not experienced enough to know what that is. I received a bayonet type even though the shipping label said customer needs spark plug CHT. After getting no luck with getting the probes swapped, EI did it for me with one phone call. If its off the shelf, youll be fine. Anything unusual like long probes or different components, go directly to EI.
