How do I install the EGT probe that came with my Exhaust Gas Temperature Gauge?Updated 3 months ago

You are going to have to drill and tap your exhaust manifold. The drill bit size for the EGT probe is a size R. After you drill and tap the hole to 1/8-27 NPT, ensure the tip of the probe is at the halfway point inside the manifold and then tighten the ferrule.
