5.0 Tuneup Time tomorrow hopefully!

[FordF-SuperDuty]

Just the coil added MPG. I keep records . I swapped new Oem in for 2 weeks to check. I have had 200000 miles on them. Ask any electronic guru to test outputs for you.

Mine died within a few thousand miles, if that.

Make sure you don't let the 2&4 and 7&8 plug wires touch. Could cause a misfire.

I used to run nothing but v powers in my flare....I won't ever run another plug. They treated me very well. Bump your timing while you're there...

How would you bump up the timing?

Basically, you'll need a timing light and a wrench. You just loosen up the hold down bolt for the distributor, start the truck up and turn the distributor in the direction to advance it a few degrees. The flareside's timing was set at about 16.5*.
