its not necessary to have it on a fairly stock car. it helps in terms of producin efficient spark to make sure all of ur fuel is burn in each cylinder. as u go fi or super na, then a msd ignition setup is benefitianary.

but if u decide to pick it up, u will need the ignition box(i have the 6al) external coil(i have the blaster 3) and an msd distributor cap.
good idea to upgrade the wires too.
