Anyone know if it can be done? Anyone do it yet?

As I recall, it is an aluminum intake, not magnesium, so it should be able to be honed right?

I have honed all my runners, I haven't bench flowed tested them as yet. They do look a lot cleaner inside. I also if you can find the post modified the early runners to suit the Euro EFI engine. These runners are shorter and will flow better as they are straighter and generally nicer. So the answer is yes you can hone these quiet nicely.

The extrude hone process isn't a typical honing process that you may be familiar with. They actually extrude or squeeze an abrasive paste through the tubes.
