MSD Ignition Digital 6AL Ignition, with Rev Limiter

Part No. 6425 Warranty Details  

Fit of this part varies by vehicle & equipment specs Type of Fit

The MSD 6AL ignition control set the standards that other ignitions strive to reach. In fact, you’ll find ignitions from other companies that carry the 6AL name (and in some cases, the same part number). For 2011, the bar has been raised even higher as we introduce the all new digital 6AL ignition control! We kept the same footprint as the traditional 6AL but lowered the profile for a sleek look. The wiring is all routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat and clean.

Product Features:
  • With soft touch rev control
  • Higher output with 530 primary volts and 135mj of spark energy
  • Efficient components use less current to produce more power
  • Set an RPM limit on the 6AL with two rotary dials
  • Same bolt pattern as the original 6AL with a lower profile housing
  • Built-in LED for system checks
  • All wires exit the same side through a locked, sealed connector
  • Compatible for 4, 6 or 8-cylinder engines

    Comments about MSD Ignition Digital 6AL Ignition, with Rev Limiter:

    I decided to upgrade my old analog MSD 6al box to the new digital 6al for my show car. I was very pleased with Advanc Auto's pricing, discount offers/promotions, as well as their delivery, but when i received and opened MSD's 6al box, and was very disappointed to see 2 things. One was that the ignition box itself was not protected by anything.The instructions were bagged but not the ignition box, leaving it leaving it unprotected from scratches from the other contents. Mine had a few minor marks and one minor scratch,and i was able to clean off the scuffs/marks, but not the very minor scratch. The 1st and most disappointing thing I noticed is that the color of the ignition box was not the same fire engine red as other MSD products (that are on my car)and not the color in their advertisements for this product.Rather it is a darker shade, I would say maroon, almost brown, rather than red.I love the quality and performance of the other products I own made by MSD, but will most likely return this item and buy another manufacturer's product. It sounds picky, but I own a show car (and even if I didn't) and other MSD products and I don't see the sense in spending $2 let alone over $200 for a product that doesn't look like it belongs. ie. Matching other products from the same manufacturer. As for Advanced auto....great Company,pricing,offers,shipping, and service.This was not their fault,but was a strange, and frankly, senseless decision of someone at MSD. PS- I called MSD=thier response was "let me see if I have one in the office, uhh Yup it looks like a different shade....."......??????

    • Q:

      Hello,
      I have a 1988 Ford Mustang GT which now has a pro built 347 Stroker. It has a 3 speed auto trans with a hurst quarter stick pro glide shifter. When I purchased the Mustang, it came with a MSD 6AL Ignition control. I noticed that the part number 6420 has been replaced by part number 6425. I want to slowly replace each part as I go and I wondered which MSD Ignition control you would recommend for this Mustang that I want to keep on the edge of street legal if possible, but concentrate mainly on strip and some drag racing. I see that there are many racing brackets that I would fit into and I would like to have the best possible multi spark system. Thank you for any help that you might be able to provide. Respectfully, Josh Kelly

        A:

        Yes, the MSD Ignition Digital 6AL Ignition, with Rev Limiter - Part No. 6425 is an exact fit for your 1988 Ford Mustang GT 5.0L. Also I would recommend the MSD Ignition RevolutionLimiter - Part No. 8732 that could be added to give racers the ability to switch to a low rpm limit to use on the starting line. Part No. 6425 comes with 135-145 mJ per spark (Spark energy), 520-540 Volts primary volts, 45,000 Volts Secondary volts. However this part is not street legal as it is a mild racing application. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
