I saw a post on another forum about the AutoTechnic oil filter adapter not fitting on newer b series motors. Just wondering if anyone is using one on a b16a2. I guess the old size was a 22mm and the new ones are 20mm, just need to straighten this out

Thanks for any replies

 

Are you sure? I think all the B series engines use the same filter, so I don't see why the adapter block wouldn't work on all B series engines. I don't know if this helps, but I'm running a GReddy adapter block on my D16Y8, and it fits both the block and the OEM filter perfectly. My Y8 uses the same filter as all the Honda engines I've worked on(B18A, F22, H23, D16Y8, B18C). Are you sure they weren't talking about the K series engines? I can see how they might have a different filter/thread size.
