Title: OEM Coil
Post by: George Mann on September 09, 2012, 05:57:38 PM
Here is a new project for anyone who feels inclined to help me.

I am looking for a non-dealer source for an OEM coil, or a reliable aftermarket equivalent.

A reasonably affordable one would help.

If you go to any of those parts stores and tell them you need an ignition coil and give them the make/model/year they will give you a direct replacement one, they should have several options on the computer for you to choose from.  It seems like you're better off spending a little extra money and going with a higher-end unit like an MSD, the bottom shelf ones often have bad reviews indicating failing within a few days, weeks, or months.

The link to the Wells one you posted on Rock Auto should be good, Wells seems to have a pretty good reputation.

Sorry guys, but the Pertronix and MSD are out due to incompatibility and being unreliable.

That's why I am going back to the stock system + TFI cap and rotor. Non of the mods have worked out. If there was a reliable (with or without resistor) high-energy coil, I would try it.

When it comes to OE that is a complicated issue.  There are OE parts that came on the car factory and thee are OE sold at dealerships which are not necessarily the same thing.  Obviously, this doesn't pertain to us because AMC no longer exists. 

There are several manufactures that manufacture for the OE suppliers and also supply the aftermarket parts stores (O'Reilly, NAPA, Advance etc.)  If you go to a good parts store and buy their premium ignition parts line you are in good shape. 

In my experience BWD and Standard Ignition are good brands and they both do OE work.

Wells used to be good but I have heard the quality has fallen down over the years.  They do a lot of "cheaper line" house brand ignition for several suppliers. 

Just my $.02 hope it helps.

I've been using an ordinary Ford coil from NAPA. It's been in use for 3 years now. I replaced the stock AMC coil and that stopped most of the random engine shutdowns. Took me until last Winter to figure out the issue with my Ignition Control Module. I'm planning on going to a very old Ford TFI dist and an MSD coil for my rebuilt 258. I have a really interesting idea that requires the brass. :)

The T connector style coils are notoriously unreliable due to corrosion at the connector. I cut the leads and put in a NAPA IC12SB coil (about $16 here) and it has double the voltage output of the T style one. That's what was on SOTE when Max98059 got it from me and it made it easy to start in winter up in Northern BC.

I second getting a Ford/Motorcraft coil. I used one myself after aftermarket coil woes. If you ask for the same coil from an 80s ford 300 six you can find them with both the horseshoe connector and with standard terminal posts.
