Ignition Coil

[delcogod]

Any wisdom on changing the ignition coil? Plugs and wires have less then 20k on them. The coil pack is probably original with 216k+ miles.

If it ain't broke, don't fix it.

ACCEL 140012 this is what i got when my Ignition Control Module Died... i replaced both and got the 8.8 yellow accel wires, you can see them in my avatar... the coil is at the bottom right corner its yellow too try jegs or summit but dont get that one its for the 2.9l i just wanted to show off

The Screamin' Demon coil pack is a really good coil pack for the 4.0. it can be had at www.stuffforyourranger.com . Wayne, the owner, is a really good guy and is heavily involved in the Ranger community.

The stock coil pack is an awesome design. If you suspect failure, replace it with an OEM or aftermarket replacement. Upgrading this design to a super expensive one is an exercise in blowing money. Pay me 300$ and ill paint flames on it and send you stickers to increase HP.

None of the aftermarket ignition part manufacturers (MSD, Accel, Performance Distributors-maker of Screamin Demon) do any kind of reliability testing on their products, which are called out by SAE. The electronic component suppliers for the big 3 (Ford, GM, and Chrysler) all follow the reliability testing standards called out by the SAE. The European, and Japanese automotive industries have similar reliability testing standards. So, for the most reliable ignition components, stay with the OEM!

Everything Bob and Skinner said TIMES TWO!! And remember... None of the aftermarket coils can do ANYTHING better for your ride than OEM!! If you really want a RED or YELLOW one..Ok get it! But if you want a SPARK...get OEM!

Check out this thread from the MSD forums, especially the last post!

With this number of calls / day, I would say they have a major quality problem!!!

You are assuming that all the calls are about a failure problem with the devices, or quality as you put it. I would bet many of the calls are about how to install, or wire correctly, or what devices to use. Some of the performance devices can be a little tricky.

I am not of the school that only the OEM can make quality products. And even with all their rigid testing, etc., they still have a garage in back of most dealerships, and tons of service bulletins.

I have had few problems with new aftermaket products. The re-built stuff is a different story.

Plus, the costs of OEM products is insane in some cases, and it sure isn't because the quality is any better. For instance, I just put a new battery cable on my Explorer. $79.shady

If what you are saying was true Shady, MSD wouldn't need this:

If reliability testing wasn't important (which the aftermarket component manufacturers DO NOT DO) why would the SAE have standards on it?

All companies have a way of returning their products, even Ford. It just so happens that MSD uses the RMA (Return Material Authorization) process.

ALL PRODUCTS FAIL, EVEN FORD, CHEVY, DODGE, HONDA, TOYOTA, AND NISSAN PARTS FAIL.

Bob is an idiot.

YUP, there is a failure rate associated with all electrical components!

The aftermarket ones just fail at a much higher rate!!!

You just showed your ignorance when it comes to reliability testing!

Guys, stop the pissing match before it gets out of hand.

Let's analyze the reasons why one might want an aftermarket ignition:

1. Performance. It isn't possible to light off a charge better than perfect, so if combustion is occurring and not fouling emissions, OEM is adequate. It DID do this from the factory; that's required to sell the vehicle. There is no such thing as better than adequate.

2. Reliability. OEM coils often last the life of the vehicle. Once again, you can't do better than perfect. In this post, there has been NO EVIDENCE THAT THERE HAS BEEN A FAILURE. So, I'll stick with my first post -- if it ain't broke, don't fix it. A working coil is a working coil.

How would you prove this statement? I don't find this to be true of the parts I use. Maybe your garage has problems due to other factors.

Also, Gross is right, in a stock application, if it works leave it alone. High performance applications is a different story.shady

Knock it off all of you. Maurice, no more warnings.
