EGT or AFR gauge and bung

[ghittner]

I have stainless marine manifolds and Exhaust which of course are wet. I need an AFR or EGT gauge and sender as well as a bung to weld in. Does anyone make the bung or should I just cut one out of stainless rod stock? Thanks. Any of these gauge manufacturers better than others? Thanks.

I got the A/F ratio gauge and the bungs from Innovate Motorsports and it has worked well. They have a web site, www.tuneyourengine.com

What about drilling and tapping into my Stainless Marine manifolds right at the bottom of a cylinder? There is enough meat there to accomplish that.
