Does anyone know what's the going rate for a ported GenII intake?

From what I understand you can't just port it you must cut it in half then port it and then weld it together. Don't know the price but it is a difficult process that not to many shops do.

Anyone done an extrude hone?

Extrude hone's been done before with results yielding 0-10hp gain as I recall the threads. Do a search

Extrude hone's been done plenty, but I don't think it was ever done all by itself to tell what the HP difference was. Its really part of a package - better flow from airbox to heads. If you have the heads done, I'd extrude hone too.

I think I saw Underground does it, check with them, but it sure looks and feels pretty when you get it done.

Heffner tried cutting open the plenums and porting the OE intake a few years ago and found the results weren't worth enough to continue to offer it..
