Spark plug Gap

I have just purchased a new set of NGK plugs and would like to know what the proper gap for a 4.0l 1990 Aerostar would be.

Now that you ask, my mind has gone blank, but I think .036 is what I use on my 90 4.0. I will look when I get home and check back with you. Or call the parts store you got them from and they can tell you.

The gap for the 4.0L is .054 in the Chiltons manual
