Hi

I have a J's racing header and it has an extra bung for a wideband o2 sensor. As i don't have a sensor the hole is plugged with a bolt. Unfornunately the bolt unscrewed itself and was shot of the other day. Now i'm trying to find a new bolt but they are hard to find especially as i don't know the type of threads. It seems to be M18 in size but the threads are finer than standard. Anyone?

Another question. I'm considering getting a wideband o2 sensor like a LM-1. Also considering getting a diagnostics tool at the same time. The s2000 is OBD-II right?

Ok, thanks. Now for the thread question. Are the threads M18x1,5 og M18x1,25. It is of importance as i have to order these.......

Can you not find the threading of an wideband O2 sensor somewhere and find a bolt from that?

Call and ask a wideband dealer what the threading is on their sensor to "confirm it'll fit your car"

That's exactly what i'm trying to do. Was hoping someone here knew and could tell me.

Calling and ask is certainly a possibility.

Go to any muffler shop. They should have a replacement plug for you. I got one from a local shop for $8.

Thread appears to be M18x1,5. Found an old spark plug in the garage that fitted in the holde and looked up the thread on the net. Ordered a few bolts. They were pretty pricey. 20$ a piece. But then again everything is expensive here........

yeah its 18x1.5
