MSD 6AL-2 Ignition Box

Summit RacingSummit Racing Verified Purchase

As always Summit Racing ships merchandise in a very timely manner...After receiving my MSD 6AL-2 Ignition box I installed it on my 1979 Mustang Cobra. The box made quite a difference in performance along with my MSD Distributor which I also purchased from Summit Racing.... Great products, good prices and excellent service from both the products as well as Summit Racing... ...read more

good

Summit RacingSummit Racing Verified Purchase

Hooked right up, no probs, would be nice if it shared the same plug ends as the 6al-2 programmable I downgraded and had to cut the plug end off my harness (controlling timing via stand alone ecu now)

MSD 6AL-2

Summit RacingSummit Racing Verified Purchase

I purchased the MSD 6421 ignition box and a MSD HVC 8252 coil. I am very satisfied with this ignition system. My car runs better than ever. My old system was a MSD digital 7520. This box failed and can not be repaired. Pros: Great box small easy to mount, great box for the price Cons: the switches for the RPM limiters are very small.

More power!

Summit RacingSummit Racing Verified Purchase

I swapped out my thirteen year old 6AL for this new digital unit and it gave me a noticeable boost in power. It's smaller in size and is easy to fine adjust without the need to buy a bunch of plug-ins. I haven't wired my 2 step yet but it's a great bonus for not much money if you're already upgrading your ignition.
