Port & Polish Intake Manifold..

[foss40z]

What do you guys think about this? I have an extra 1 sitting around and im bored.. Would doing a port and polish to the intake manifold provide better anything? or will i be just waisting my time and tools..

What kind of HP and MPG can be added if done..

Not so much that you would probably notice on a significant level HP wise, MPG's might hold up better.
Port matching would prolly show up more...maybe ...depending on how healthy your 2.9 is.

If your really bored...do it...then compare for yourself.
to really show the improvements before and after dyno testing would be in order.

A smooth intake tract is what fuel injected motors like.....but like IM said,any gains will probably be small.

I agree with IMenriched, port maching would show more then just polishing.
