I just installed my Sparks mid-pipe. I need to find some bolts to plug the two holes. I need to know the bolt thread sizes. One on the front pipe is about a 10mm and the O2 hole is an 18mm. I'm only guessing the 18 is a 1.50 pitch but have no idea of the 10mm. A normal 10mm x 1.25 pitch doesn't fit.
it's 10x1. i lost mine and put a home depot stainless bolt in it until i picked up a new one. used a hacksaw to shorten it.
use copper gasket and thread antisieze.
Thanks for the quick answer. Was the 18mm a 1.50 pitch?

i am not sure because those sensors are all the same, FWIR. i am pretty sure they use "Fine" pitch for everything for better sealing which should be 1.5 for the 18mm.
Thanks! I can't believe how hard that thing is to find. Even Fastenal is having a hard time. They might have a long one that needs cutting down to about 15mm. I want to start that beast now!!!
I want to car craft last week and they went out back and took 2 plugs out of exhaust they had and sold those to me. [thumbsup]
