MSD Spark Plug Wires

[Anonymous]

While making up a set of custome length MSD wires I saw something that wasn't quite write. The end that came pre made up for the coil (pre made end goes on the coil) had a brass connector. This is weird because the set that I made for my I6 two years back I remember that mine came with a steel connector. So I investigated and sure enough mine was steel; when I returned to the box of connectors for the new set of wires and looked at the instructions I discovered that the steel connector was for the spark plugs. So I grabbed a spare coil and tried to insert one of the unused spark plug conecters, low and behold it doesn't fit and the brass one does. Because the boot fit so tightly I never noticed that the conecter wasn't fitting into the socket; which explains the years of inexplainable rough idling. As soon as I changed it to a brass connector I noticed a difference in performance: smooth idle, more low end torque, hopefuly better gas mileage, when accelerating from a stop going straight with the throttle depressed at leased 3/4 it will cherp the tires going into 2nd; and I have an automatic.

I always plug the connector into the socket, then slide its boot down the insulation to cover. Sometimes a little "303" wiped on the insulation makes this easier, but I keep the actual "tower" clean to maximise friction.

That the lead tips are fully "home" is one of my first checks when a car won't run well.

I had a similar problem with the boots of my MSD wires actually being so tight on the distributor cap that they forced the internal wire connection up a bit. Some arcing was evident. I squeezed down on the brass fitting and used Di-electric grease on the boot. Now it stays tight into the distributor cap.

Also had a MSD wire shock me when I touched it. Got it replaced for free and hopefully will cure my high speed miss I had.
