Hey I'm thinking about buying a JDM Itr intake manifold for my obd1 first gen b16a. I heard that the JDM itr intake manifold has one extra vacuum port. If it does how am I gonna set it up to work my b16a? Any suggestions would be appreciated. Oh ya I did search and no one seems to know anything.

 

If it has extra vacume port you plug them with a rubber cap

 

If I use it and plug the vacuum port you guys think I'll pass the at the smog ref?
