Anyone out there running these coils in their Mustang? Looking for feedback and/or reviews on them. My car has 128,000 and is running fine but I am going to change the plugs and figured that I might as well switch to these since they claim better spark, fuel economy, etc! Are they worth it? I am looking at the NGK G-Power plugs by the way!

The general consensus here will be to rebuild and use the OEM Coils.

I repeat. Do not buy those. I had them less than a month and one of the boot ripped/torn causing a misfire. Replaced all msd coils with oem Motorcraft and it runs soooo much better.

I put MSD wires on a Chevy truck I had some several years ago. Ran fine for a few weeks and started misfiring. One of the boots split and was arching fire all over the place. I'm not a big MSD fan personally.

Wow! All negative reviews...I would not have guessed that! Thanks guys! Any spark plug tips? Like I said earlier I have my eye on the NGK G-Power Iridium plugs.

Rebuild cops like other said, order from Rockauto with the forum discount of 6%. Just use Motorcraft plugs too, go OEM the parts are better in this case with the COPs and the plus. The NGK would be fine but not worth the money for the snakeoil

I had a set of MSD wires on my truck for over 300k miles. They were purchased in the mid 1990's though.
I've noticed a steady decline in the quality of parts that companies such as MSD and Accel have been selling, over the past couple of decades. I guess that they can make more money peddling cheap Chinese garbage, than they did when they were having their mediocre parts manufactured more "locally".

The stock Motorcraft spark plugs will work fine.
There is no need for anything fancy unless you are pushing a lot of boost.

I have those and have had Absolutely NO problem with them at all, for me they are Flawless, car runs better, more responsive etc. My vote is go with them.

Lol.
You have a hell of a lot more than those coils to make your engine seem more responsive!

I'll bet that if we did a "blind" test, and swapped between the MSD and Motorcraft coils on your car, that you wouldn't be able to tell the difference which coils were installed on your car.

I've got MSD on my car and have zero problems!.. I've used Moto Blue, they were decent!.. And Accell, they ended up being total crap!.. If you don't have problems with your stockers, then no need to replace!.. One of my stock coils completely fouled out, that's why I changed them!..

In your case, I would bet that you did indeed notice an improvement in the way that the engine ran.
There is no difference in the performance of aftermarket coils compared to OEM. The only seemingly "advantage" to using aftermarket coils is that they are typically less expensive than OEM coils... They are also typically much less reliable than OEM.

Do you have Cliffy's site saved in your favorites? I swear I can never remember the name of it until you post up a link

No issues with my car at the moment but with 128,000 miles I was figuring that it was time to change the wires and plugs (preventive maintenance)! From the sound of the advice here it seems best to go OEM and call it a day...no major advantage with aftermarket and a higher possibility of failure! The NGK plugs are $3.50 a piece so that isn't breaking the bank! Thanks for all of the info!

Accell and msd coils aren't really complete crap. And if you change worn old 12 year old motorcraft for fresh new product, you will probably notice a difference. But brand new for brand new, the motorcraft will be unnoticeably better, and have much higher odds of lasting way longer. Like another 10 years vs a 2 month to 2 year range.

As for plugs, ngk makes a good quality plug. Oem motorcraft were designed for our engine to ford's spec. But ngk also designed theirs to meet our oem specs. You will be fine with autolite, ngk, and motorcraft. Preferably motorcraft in almost any situation though.
