I really don't want to drill another hole on my header just for the EGT probe. Is there an adaptor I can find to make it fit to the existing hole for the 02 sensor? Or better yet, is there another way to install the probe without drilling a hole?

 

What would you do with the O2 sensor then...?? :confused

Well, you could put it in your tailpipe, lol...but I'm not sure how accurate your reading would be...:

 

Well, I'm actually looking for an adaptor that splits to 2 so you can connect the 02 and the EGT probe to it.

 

No, you're going to have to drill/tap. It's no big deal at all to do - it's a really easy job.
