Hey all. I have a set of SLP's I'm throwing on my 85 sport coupe. I have a 406, so I'm not running the computer or anything, and I need to plug the O2 sensor bung. Now, of course, I didn't think of this until I installed the headers, so I can't measure it. Anyone know what size plug will fit??

Thanks

Dave

 

It should be an 18mm plug. Thunder Racing stocks one. Here's a link, http://www.thunderracing.com/index.c...tegoryid=1034. The part is designated 99-02-PLUG. You should be able to find a plug local though. Hope this helps.
