O2 Sensor, What Size!

[GTS4dood]

Morning All!

Im currently tryin to purchase a new O2 sensor for my R32. going through Petroject as i found them mentioned on one of these forums as having one that is a straight fit. when i called them the guy said he needs the size of the hexagon bolt or something as there are different ones. As i wont be able to get to my car til next week i was wondering does anyone know the size already so i can order it straight away. he said it would be something like 17mm/22mm

CHEERS!

I just called Petroject and the guy said that the only O2 sensor he can find is a 21mm hex head bolt one. its for an EL falcon. i thought that these were universal to RB20's but it doesnt look that way. odd as ive talked to ppl that said they have used these!? Does anyone know were the hell i can get one that will fit. or just someone that has swaped it over and might know something that im missing????

Sorry for the confusion, the 17mm is for a 32 rb26 not rb20. Not sure about the rb20 one but the EL falcon definately fits 33 and 34 rb25.
