Not Ranked
yep
Hi Liam,
Yes your right the rubber tubing is metal ribbed and yes it would create some turbulance which is why I went for 90mm id whilst my throttle body is only 75mm id.
In regards to surfaces. The inside surface of the intake should not be too smooth either as this will also create turbulance as the air will stick to the smooth surface.
