i still think there not worth it, but if you guys insist on buying them i am an apexi dealer, i believe we sell those for $225 US plus shipping. but for less than that i can get you guys a 68MM throttle body. throttle body you can just put on, with the ground wires you need to know exactly where to ground them or you need a dyno to find the right spots, which can be time consuming and expensive.
