whats the best intake manifold for a dseries?

 

y8

 

y8 hands down, nothing else comes close.

 

can you just bolt up a y8 mani to a d16a6 and keep obdo or do you have to change a bunch of ---- to switch it from obd2?

 

any my question, can i use a y8 on my z6?

 

yes you can.

But the real best manifold is a VENOM or Skunk2 racing manifold howahah Or build one yourself

 

I've got the skunk2 I can tell you it will flow probably 20% better then the y8.

 

Chop your stock one and weld a fatty plenum on for boost, it will smoke a skunk2 mani, and will be compareable to a Venom Manifold.

(only if this is for FI of course) because larger plenums are really only good for FI.
