Question: What is the difference between the webbed ZX FI intake and the unwebbed 280 intake?

Is the webbed one square port because the P90 is? If this is true, is the intake that came off 75-76 N42's also square? I have not seen a webbed intake on 75-76's, so does that mean there are three different N/A FI intake mani's? or 4? (square for n42, then round for n47, still round for P79 and then square again for P90?)

All the Z intakes have round ports. Only the exhaust can have either round or square ports. I don't remember what the story is on the webbed intake manifolds. I know both the 280s I have had ('75 & '76) were with the non-webbed style.

I would think the webbed manifold would hold more heat, would make working around it more difficult(harder to see through), would be a little heavier and I don't care for the look much.

Just my thoughts.

Have fun!
