My current performance mods include K&N Intake w/ heatshield, flowmaster 40 series, and 75mm intake (soon to include the throttle body elbow being ported).

Those dont equal much at all I'm sure in the HP department, but they scored big in my SMILE department! I'll go the way of tuner/chip next, and when I'm making the big bucks next year... supercharging/N02
