DIY: Z1 Intake Plenum and Spark Plug Swap [Picture Heavy]

Mozen, looks like you could use a catch can? That first runner looks dirty from the PCV hoses coming in right there with oil and blow by.

Does it look hard to pull off the 6 runners the mani bolts too? That cast piece looks rough and could use a PnP too! Might pick up some more power. I want to do the TB, mani and runners all PnP.

Is it possible they are flow balancing the runners as well? Just looking at the variable ammount of grinding that looks like is being done to each runner (Hard to tell for sure from the pics).

For $300 I doubt it. Would make sence though for optimum performance.
