I recently purchased a set of lg headers for my c5z. While installing I noticed that the o2 sensor bung on the driver side header I'd at the wrong angle and I can't get the sensor in. Anybody know what the angle needs to be at so it will work?

 

EXACTLY 133 degrees.

Squared.

 

Talked to lg today they're going to send me a new header.

 

I guess I really didn't understand your question. Glad they're sending you a header.

I would have guessed the o2 bung was either tapp'd wrong or maybe you cross threaded it.

 

It was mounted in the wrong spot by lg, I couldn't even get the o2 sensor in the bung to try to thread it, but out of the car it would thread in fine.
