I find it odd that on the Volvo sites there seems to be an obsession with removing things that block the air flow to the radiator of turbo charged cars while we seem more to fill up that space with horns, extra radiators and big K and N filters on DCAI systems.

I would at least like to move the horns out of the way.

On topic, on the hottest of days I run needle width above horizontal after a highway run.
