I was genuinely curious as only one other forum member had done it. Curiosity cost me $900+ all said and done. $350? for IM and $600 for the extrude-hone service. That was 4 years ago, I don't want to think of what it cost now. Personally worth it. But I'd image we are only talking about another 6-10hp here.

OK - I could buy that on a supercharged motor it could be worthwhile. 6-10 hp sounds a bit optimistic, but *maybe*...
For an NA motor, though, I don't think it would see any significant gains - just not moving enough air to need more flow.

Wait - are you saying you felt there was a
6-10 hp gain NA up top with the Extrude Honed 2017+ IM?
Was this vs. your stock 2013 IM, or the gain from doing the Extrude Hone on the 2017+ IM vs. not Extrude Honed?
