Aero Space Logic 4-channel cylinder head temp gauge. Monitors all 4 cylinders head temps with either a scroll though or display hotest function, I believe that it also has a setable alarm. I purchased this from Chris at Tangerine Racing but have sold my car since then. Probes are meant to go under the spark-plugs but can also be put under the head studs for less work when changing plugs. $485 from Chris will sell for $275 shipped.
