I think this is a great mod. 2 1/2" shop-vac hose work well. Pull all the plastic crap out of your fender well and grind out a little arc in the sheet metal where it crimps the hose under the liner. (You'll see it...) MTX problem: When you have strong air flow in your hose, (around 50+ MPH) and you push in the clutch, the idle will drop and possibly stall. Solution: Leave a 1/2" space between the hose and the KKM center cone. You'll still get cold air, but less turbulence to confuse the MAF.
