I have a ram horn ex mani and I was wondering where the best spot to put I egt probe at?

Thanks

 

Flip the manifold over weld the provided bung onto the number # 3 runner space it about .75-1" from the flange. Drill a hole one size bigger then the probe then weld the bung on and install the adapter then probe.

It kind of depends on what you're using the probe for. Trying to make sure you don't melt a valve? Analyzing cylinder to cylinder mixture distribution? Measuring delta-T across the turbo?
