Was thinking of getting a msd ignition box but not sure if its worth the benefits or not. I tried a search but didn't come up with too much. I know some of you guys have them, see any difference at all?

thanks

 

I noticed my car reved up quicker thats about it.

 

If you have a fuel injected engine than it is not worth it. It is worth some gas mileage on a carb though. When I had it on one of my old efi'd engines it only lowered my MAP readings by 1 or 2. So I eventually just gave it away to a friend.

 

I bought the 6AL for my 92/ 305TPI. I saw 11 more miles from a tank of gas, faster startups, and better idel. I think it was worth the money. If you do get one I would by the wiring harness that MSD sells. It plugs right in to the factory harness so you don't have to cut any wires.

 

thanks for the replies, I'll look into it some more but I'll probably get one later one.

 

if you are a gadgety type of person who buys gimmick spark plugs like +4's sh!tfires, rapidcraps etc.....
save those pennies and get a 6a, two sets of plugs changes come close to what this box does, and it will help

i have it on every car, one is better start up (of maybe not something that is a huge benefit)
does help out when under load (in the case of a truck or towing)
excellent for modded motors, like big cams, forced induction etc.)
super easy to install
and slight gas mileage increases, minor in a FI car, noticeable in a carb car.
could help if you are border line on passing emmissions
just my experiences


negatives:
price
wiring time
burns caps and plug wires quicker
