The leads are only 4 feet long so there won't be enough of a lead to get to number 4 jug without a patch. The patches are not cheap. This is one thing, list, you Must Be Aware of. CHT and EGT meters measure wire resistance, which varies with with the heat. To get an accurate measure, you measure the resistance of Both the bi-metalic junction And the wire to the gage! Thus, "A Patch" costs so much not just for the wire, but also for the recalibration of the meter. Percy in Portland
