@Ironracer I don’t know who you but so far I only commented on what a company offers and NOT what is OK to use on an engine as far as any tubing goes and what size it should have. Not even if it was advantageous over a scoop.
Since the mention was in reply to someone else’s mention of this device, I only answered and questioned in the same reply.
The device in question is normally seen with two vent tubes that help bring in cool air from down low which would (and should) be a power gain over the engine ingesting hot under hood air.
Stop assuming
