Apparently so!!! Haven't had a real good look as my heatshield is on, but simon (cossy racer) reckons it is. He had a look when I was up getting some driveshafts off him. The lambda sensor pokes straight up out of the ex housing. I think I can see .63 written down by the mounting flange. How do you know BTW?? (note to self - find out more about my own car!!!)
