MSD Ignition box 6A

I just purchased a MSD Ignition box #6A for my 1993 F-150 with a 5.0 L and a E4OD tranny. I am running the MSD Coil, 9mm Ford Motorsport spark plug wires, and I was curious what spark plug gap you guys are setting your's at with this box?

I don't know if the fact that I have a K&N air filter, a 3" high flow cat or the timing set at 12.5 degrees makes a differance.....but I figured I will give you all the info the first time. Thanks in advance.

I'm not sure what gap you should use but I'm getting ready to buy the same MSD setup. How do you like it? How was the install?

The instructions tell you what to set the gap at I believe.

I like the setup........it runs better and has improved my throttle response. I have a 302 with 4:10 gears from the factory in a shortbox, standard cab and it tows better and gets better fuel mileage than my 1997 Expedition with 3" exhaust, Diablosport chip, K&N intake and Helix throttle body spacer on a 5.4L.

As for the install I would highly recommend the Ford TFI wiring kit. It took me 10 minutes to install but an hour to figure out where I wanted it. I finally mounted it were the jack and lugwrench go and threw them in the truckbox I have mounted in my bed.
