B207 Exhaust Cam Cover. 
When you use the B207 head on the Z22SE there are a couple of things which you need to do. 
The B207 head uses a longer exhaust cam than the Z22SE and as such it means that you either need to use a B207 exhaust cam or if you want to use a Z22SE cam you need to block it off. 
Made from 5mm laser cut aluminium and included, 2x M8 SCH bolts.
