If i wanna install a msd ignition box will it work good for a v6 firebird? i got the 6AL model!

 

Just need a wiring harness.

 

how much do they cost n where can i get it?...will it do anything power wise?

 

If I were, I wouldn't buy one. You will see no gains and it will do absolutely nothing for you know. Just an expensive $200+ piece of metal/plastic sitting in your engine compartment. You won't notice anything unless you've got your car modded up. You may notice smoother idle and better top end.

 

a 6AL wont work, you need a DIS 4 to work with a car that is equipped with a 6 cyl DIS car
