go with corksport, I personally have a cobb SRI, but have tried the corksport and its unbeatable for the price. Order it from ken at PG, as he has them at an unbeatable price.
Tell him Jeff sent you
The bracket that holds intake is mounted to the battery box. The engine rock causes the piece on the battery tray to break. It has happened to many members so far but mine is OK for now.
i installed the corksport intake a month ago. I think is great. increased horsepower, better acceleration, the car revs up faster. now I need to upgrade the side mount or install a torque damper to control the increased wheel hop.
be careful when instaling the hose that connects to the wasegate contoller. It is a small plastic piece that brakes easyly and cost around $80 to replace.
