my stock coil pack has a crack on the side of it and this is a common problem for these coil packs. i wanna know if i should go with a oem coil or aftermarket one, but are they more durable than the OEM one?

my ford dealer that i work at can get me a stock coil for 72 bucks
and idk what msd or screaming demon are going for.

what do u guys think like pros and cons

MSD is about $75 now at CFM. If you plan on keeping it mostly stock the Ford coil pack should be fine. The price you gave is pretty good. On a mostly stock motor a coil pack change is a small difference and a lot of people wouldn't even notice the change, unless the stock one was malfunctioning.

The only difference I saw between the stock coil and the MSD is a bump in fuel economy. I gained like 3 MPG.

Another thing to factor into the cost of changing to an aftermarket coil is you'll need new wires to match up to a different post style.

Screamin Demon is terrible; don't even consider it. MSD is a good brand, but unnecessary for the Focus because it doesn't improve anything; plus you'll be stuck using only MSD wires. Stick with OEM/Motorcraft. Call Steve at Tousley Ford to see what kind of price he can get you: 1-800-328-9552

This is a blanket statement that doesn't apply to the Focus. The stock coilpack is used on plenty of high-horsepower turbo Focus motors with no problems.

The reason you saw a bump in MPG is because you replaced the wires at the same time, which would happen with the stock coil, too.

OEM all the way, don't waste your money!
Quality advice right here. Don't waste your money on ignition coils... the OEM one is very robust and can handle just about anything you throw at it.

I disagree, seeing as how I replaced a set of brand new Steeda wires (that Missourileo is running on his now) with a set of CFM wires. I actually downgraded in the wire department. However, because of the stronger spark I was able to overgap my plugs. Bigger ignition source = faster and more complete burn.

It's been proven that the MSD coil doesn't give a stronger spark than stock on the Focus; you'd have to search through a few years of posts, but I've seen it posted on here before. Gapping the plugs gave you better MPG then, and plenty of people do that on the stock coil too, including me (before the supercharger). I had mine at .065 with a stock coil and Taylor wires.

Personally for the extra 3 bucks I'd go for the MSD just for the fact that I have used them on other vehicles and they are fantastic (increased MPG and throttle response) so I don't think it would hurt.

I don't have them on my SVT yet but it will happen soon.

FOR THE LOVE OF GOD STAY AWAY FROM SCREAMIN DEMON

aftermartket coil

Ok. correct me if im wrong here. But, i think you can use the msd coil on an svt. instead of using the matching msd wires i believe you can use a set of regular zx3/zx5 wires. they have the same towers on the coil. also i cant tell you whether or not they (msd) increase the performance or not. My svt had the msd componants on it when i bought it. hope that helps you. later.

I didn't say the stock coil couldn't be used on high horsepower motors. You should read and understand all the posts in a thread before you go spouting off. I was just trying to help out and answer the question he asked not bash on everyone that is trying to help. I guess we don't really need a forum here . We can just send direct inquiries to Cayse , 'cuz he knows everthing.[neener]

Who's spouting off or bashing? Jeez.

djohn, the MSD coil has proprietary terminals, so you can only use MSD wires. At least it was back when I looked at them, which was a few years ago. Either way, you can see from Mother Focus' post that the MSD coil doesn't perform as well as the stock one.

Coil

I bought a Standard Motor Products coil from rockauto.com, I doubt you could measure any horsepower improvement using a high output coil or wires on a stock or mildly modified engine.

CaysE, why do you consider Screaming Deamon bad? My SVT came with screaming deamon coil and live wires, ive never had the stock coil on. It works good for me.

I bought it when I first got my car and had intermittent missing issues. I swapped it out for stock and never had a problem since, even with the JRSC.

Its simply like this... You can either put a stock coil back on for $45 or a MSD for almost double or more since you HAVE to buy new wires...... and theres no performance difference between them.

So obviously some of you are, and some not. For those of you using MSD part 8241 (coil) that also requires part 32939 (wires); how many of you have it tagged up with part 62112 (ignition).

I've used msd before when I had a 92 Ford Explorer, and liked them then...

SD and MSD both use ZX2 wires (which has been covered numerous times). Both are the exact same coils used on the SOHC 4.6.
Stock coils are rated for ~50,000 volts. MSD/SD are rated for about 55,000 volts. No real difference.

Larger plug gap = more ignition lead time = higher injector PW = higher fuel consumption but more complete combustion which can lead to less throttle and better MPG.
