Kamikaze header bung
I bought a Kamikaze header for a race application of a zetec. I am a little perplexed by a bung on the header on cyl #4 runner. Does anyone know what this is for? It doesn't appear to be an EGR bung since that one is a female (not male) on the stock header. I'm primarily looking to cap it off, so if anyone knows the thread size, I'd really appreciate it.
Emailed the manufacturer - no response. Their number is disconnected...go figure.
