Subaru Impreza WRX "Sti"

How it was Used: Wrinkle red short ram intake system with a heat shield. The mod itself doesn't really do much as far as performance with the current set up I have. But it does inhance the sound of the stock blow off valve and the spool up of the turbo. At the very least I've noticed a slight increase in spool and throttle response. The performance most likely won't be very big until an ECU upgrade and downpipe are installed.

Price Paid: 180

How it was Used: Carbon Fiber Driveshaft from ACPT. This should provide a % increase in performance across the board. It also reduced the weight of the car by about 20-30lbs.

Price Paid: 900
