I'm looking at buying a set of these cams for my boosted b16 build, there are a pair for sale on eBay but how can I tell if they are genuine without measuring them? Are there any part numbers on them I could ask the guy to check?

 

type on google itr cam id and you will get pictures..

 

Thanks, I have seen the pictures with the rings on the end just thought there may be a part number on the side.

 

No part # stamped on OEM cams or any cams. Only way to identify is measuring them and pictures.

Depending on which year you are talking about. The designs will be slightly different on the intake cam.
