Ignition coil upgrade?

#7
I'm on stock coils with the Granatelli spring replacement upgrade. The stock coils fire at 16,000 volts. They are sufficient for 700-800hp. The MSD coils fire 10% higher at 17,600v. The only coils you can call an upgrade are the Graneteli which fire at 60,000v. Even at my power level there is little to be gained by doing this but I probably will when my Motorcrafts die.
To the op if you want more fire power you should go with the MSD ignition box for 6cyl motors. It will fire your factory coils significantly higher. But don't expect huge power gains. You might pickup 5hp on a factory na motor and maybe a lil mpg increase. Factory coils get the job done right now days due to strict emission laws and mpg requirements.

And while you're at it, you may as well look at plugs & wires. That's if anyone still owns a 4.2.

On the off chance that anyone still owns a 4.2, the OEM Ford Motorcraft part has dropped in pricing to well under $100. MSD is about $100. NGK & Denso offer units for about half of MSD pricing. When you look online, off brand parts can be found in the $20 price range.

And, I still own my 07 F-150. 4.2 V6. 147K miles and still going strong!

For the most part, that is true with most cars. You can't go wrong with the OEM parts. Most of the over-the-counter stuff at auto supply chains just isn't that great. Champion, Fram, Duralast, Autolite......wouldn't work well with a Ford, or Honda, or Mercedes, or any other car, compared to the OEM part.
I remember once buying a "Car And Driver" licensed, branded battery from an auto parts store, because the car was such a junker, and I only wanted to install the least expensive battery.
At about $3, the Ford Motorcraft spark plug in a Ford is hard to beat. It's the OEM, and it's cheap. There is room for improvement beyond OEM performance. I think it's worth the money to buy an Optima battery. I spend extra money for drilled & slotted brakes. I'm using a Goodyear Gatorback fan belt. I think you can do better than the OEM Hankook tires. But it's harder to justify upwards of $20 for an oil filter when Ford is about $3. You cannot save any money using Wal*Mart Super Tech filters.
I like using OEM whenever possible, and when it's efficient. However, I'm open minded to using other products. I just bought an AC Delco fuel filter, and AC Delco wiper blades. For whatever reason, pricing was about 1/2. I'm currently using E3 spark plugs, because I got them for $0.88. I have a MSD coil, because I found it on sale for $75, when the Motorcraft was $110 Is the MSD any better, in any way? No. Just a little less expensive that day. I have used all sorts of brands of Mercon V......As long as it says Mercon V, I don't care if it's Wal*Mart, Pennzoil, Castrol, or Amalie. Whatever synthetic blend or full synthetic is on sale, and I have a coupon, is what I'll use as long as it is 5W-20 or 0W-20. I've added 5W-30, since i had some left over, without any issues.
I am pretty certain, that over the years, none of the extra money spent on boutique brand oils has been worth the money. I was young, enthusiastic, had long hair, sideburns, and a moustache. Jim Jones was serving up Kool Aid in Guyana, Dan White was on a Twinkie diet, it was "The Golden Age" for adult videos, and I drove a Mustang II. Nobody understands the Quaalude Era.
