This auction's for a pair of custom made inlet manifolds for the 24v BOB engine. They may need minor fettling as these are the prototypes. They have a set of Jenvey SF 42 mm throttle bodies sitting on top (not included).  

The last pair are in stock at Boost Performance and it may be some time before I make any more due to the foundry closing shortly.

Any questions, email me and I'll try to help.

I also produce a BOA/BOB plenum intake assembly as well as top feed BOB fuel rails.

Good luck.
