Alrite i buddy has a 03 AC 500i 4x4..

he wants more power out of it..

he wants to exhasut, jet, filter, clutch it..

the speedwerx site says the kit is for an 04-07 will it work on an 03?

or is there a better setup to go for, for under 500 bucks?

also does anyone know if the speedwerx kit comes with an ignition or not?
