Msd 6AL ignition box

Summit RacingSummit Racing Verified Purchase

My first time using an ignition box. Was surprised at how much better the unit made starting, also makes motor smoother, more responsive, and burns fuel better. Wow, I'm impressed. Instructions to ignition box are simple. Easy to install. Quality is great, but most of all, it works. Glad I made this purchase.

Watch for differences when replacing old 6A

Summit RacingSummit Racing Verified Purchase

Aloha All, Replaced an old 6A (failed power lead as it would turn out, fixed and it is still working!). Not a drop in effort. 1. The case size different - Same length, however, it is wider (1/2" or so) this means having to drill out new holes and in my case move washer fluid bottle. 2. The leads now all go to one side (the bottom for me). This again, meant changing leads as they did not reach the new location as thy did before. Oh well, this is hot rodding! Mahalo, Michael ...read more

Smoother idle, more power and better emissions. I have no complaints and easily passing CA smog is just a plus.

Great upgrade for an HEI system

Summit RacingSummit Racing Verified Purchase

I replaced my streetfire HEI system with the 6AL and a pro-billet distributor. The change has not only made the car start quicker but it also runs smoother and more efficient. Since it burns the fuel more efficiently my system has leaned out a little. Nothing that a rod change can't fix. The engine feels like it has more power. Definitely recommend! ...read more

Worked like a charm.

The Rev limiting switches are impossible to see, especially once the unit is mounted. Hopefully MSD will address this design issue eventually. I did like the new pluggable wiring harness, and the unit worked flawlessly, however I was replacing a 6a with less than 10k miles on it, so not sure the quality is where it used to be.
