Ignition Coils - Which to get?

metroplex · Nov 28, 2007

I have a 00 NPI motor that uses the Coil On Plug ignition coils (COP), which is the same as what 99-04 GTs are using (well, I suppose the same as 05-up GTs as well).

Are there any good/reliable aftermarket COP coils that I should buy? Or should I just stick with eight replacement Motorcraft coils? These look quite expensive at nearly $400/8. How are the MSD coils?

What's wrong with the ones you have?

I'm getting a P0300 random misfire code and these coils are about 7 years old. I suspect it may be caused by a few bad coil packs.

Id get the MSD's if you are going to buy a set of 8

Dont buy granetelli. I bought them and had two bad ones from the factory.

Turns out a lot of people get P0300 with aftermarket cams: from GM's 3.8L Series II V6 Grand Prix owners to other Mustang owners. I am going to disable P0300 and try new COPs from eBay to see if it solves the rough idling. Thanks for the tip about Granatelli. I've read a lot of bad things about their products on The Mustang Source.
