Johnson/Evinrude Pyro Studs

This stud kit is a must for installing individual cylinder pyrometers. Kit comes with a drill guide and provides a passage way through exhaust stud to invidual exhaust port. It is vitally important to install each sensor at an equal depth in the port. I cannot stress enough that each sensor needs to be at the same depth to get accurate temperature readings. Uneven sensor depth installation will affect temperature readings dramatically indicating a problem that might not actually exist.

Price: $175/per 6
