Extrude honing TPI Intake runners
So this article just hit Jalopnik, and while the GIF and Poster pic they posted is for a Mustang 5.0 the Youtube video starts out with a VERY familiar part to Thirdgen owners.

Re: Extrude honing TPI Intake runners
Saw that on FB. Can't imagine the hp increase on stock tpi runners being worth the cost at all.

Re: Extrude honing TPI Intake runners
I think its cool more from the industrial process because we hear about it all the time.
On a stock engine, it would be a really small gain probably not even measurable.

Re: Extrude honing TPI Intake runners
Yeah seems pretty useless all things considered. I might consider doing it on an aftermarket set but stock parts? Waste of time.
