Accel COP's

Ok, so my COP's started dying with 170k on the clock, not really surprised. For the price, I decided to try the Accel COP's, got them from Jeg's for $24.99 each, very cheap IMHO. So I installed them, and they ran great.

Now, 2 months later, the plastic casings have cracked, and 7 of the 8 are mis-firing. The have been sent back, refund is on the way. Just thought I'd provide some input for others who may decide to give them a try.

Also, MSD has COP replacement's out now too, around the $50 price range, and I wouldn't hesitate to try those myself if I hadn't already installed OEM's.

$24.99, wow that's cheap. Let me guess, "Made in China?"

I've replaced a number of these on my Expedetion like everyone else here. I saw another post that said to measure the coil with an ohmmeter to make sure it's open before you replace it; they were saying the plug wire can get corroded and build enough resistance to cause the misfire under load.

I haven't had any issues since to check this out, but the next time I see the problem I'll check it out this way before I just go off to buy a new coil. I've been buying the coils at Advance, they're about $50 there.

Whoever at Ford designed the locations of these coils should be sentenced to a year of changing them out over and over as punishment for laying it out this way.

Is the entire factory COP dying or is it just the boot? I've heard of a lot of guys replacing the boot when the coil itself is fine.
