First of all its a 13B Injection lower-manifold...

This is looking in at the left side of the lower intake manifold....

What is that screw-like looking thing with a hole in the middle that is a bit out of focus?



Thanks!!

 

5&6 port actuator thingy.........................

 

hmm thingy? I dont have the sleeves in there, so its just flowing all the time... just wondering if that hole there needs to be plugged?

Cheers

 

You will find a similiar hole/broken banjo bolt on the opposite end of the intake. since the system is isolated for the 6 port actuators, you shouldn't need to plug it. The S4 has a tube and flange coming off of the exhaust that my need to be blocked off, not sure about the S5's.
