Here's the GPR I would recommend:http://www.google.com/aclk?sa=l&ai=C...ed=0CEMQpyswAA
It is same size as stock with 100% duty cycle. Smaller and much less expensive than the Stancorp monster. I bought my turbo blanket from ThermalZero. T4 size. Fits great, made in US, high quality, and allowed me to eliminate the rattling tin heat shield! Intake modifications involved adding curved pieces of aluminum to channel air better into rectangular plastic intake ports. Since box sits directly above radiator, I cleaned the whole thing with alcohol and applied foil type high heat tape with flame proof adhesive to block heat. I also cut 2 - 3/4" x @6" rectangular holes in plastic right above grille. covered them with 1/4" mesh to keep bugs out of filter. Basically, air can now travel between hood and grille more directly into filter box. Works great, been through all kinds of rain, sleet, snow, no problems even when my Wicked Wheel 2 is whistling like crazy! I also deleted my AIH because it doesn't come on unless several parameters are met including the parking brake must be engaged! If you don't sit idling in winter, you can free up 25% more flow. Also went with RiffRaff CCV inserts, boots, and T-bolt clamps. Without the stupid resonator box and the tin shield, you can reach in from the doghouse and change the fuel bowl filter in 5 minutes or less too.
