RS Airbox

[HPRS230]

There's a good article on auto speed called something like "eliminating negative boost" where an adelaide guy make some real world measurements of the intake system of his Saab turbo and the biggest restrictions were the airbox and the air flow meter.
the standard paper filter gave a very small amount of restriction.
the aim of any intake mods would be to have full atmospheric pressure at the inlet of the turbo at WOT and max rpm

I can vouch for this mod. Did this to my vRS and could defiantly notice a nice induction note from the engine. A must do mod!

How did you make the cut in the air duct, with a dremel?

Yea Drill the top corners out, then a Dremel or multi tool cutter, clean up with a blade or file.

assuming you left the grill in rather than take the whole front off?
