    Review & Install Video

    So the Screamin' Demon Coil Pack that we're working with here today is gonna be a good option for any of my 4-liter owners out there that are looking to add a quick-to-install and relatively inexpensive, mild performance mod. Now, this will improve your throttle response. It's gonna help your plugs burn fuel and air better for a little bit more power, and it'll even help with fuel economy a little bit, too. And when it comes time to throw this on, you are gonna be looking at a very easy one out of three wrenches on our difficulty meter here, about an hour job from start to finish with basic hand tools. We're gonna show you how coming up soon.So squeezing more power out of a 4-liter V6 requires a little bit more creativity, and that's where your air fuel and injection systems come into play. Now, the ignition side of the V6 is comprised of some pretty cool parts that can add surprising performance, and this is one of many ignition parts that we carry here that are gonna help your car run that much more effectively. Some factory coil on the car is more than enough for your daily driving or for your grandma, maybe your sibling's first car, if they're lucky enough, but it's just not something that was designed and engineered with performance in mind. Enter Performance Distributors and their Screamin' Demon, this part's been on the website longer than I've been employed here and it's one of the best-selling ignition mods. There's good reason why here, guys. As the name implies, this direct replacement upgrade was designed to dramatically improve ignition and spark plug voltages for your Mustang, much better combustion and cylinders. Now, that means better starts along with improving horsepower, torque, and throttle response. And something I like about this coil aside from the price, which we'll talk about soon, is that if you're to pair them with the fresh and the spark plugs, maybe even a set of spark plug wires, everything here is gonna work together really well to give you that much more of an upgrade in performance, and it's something that's apparent once you get back behind the wheel.So, now that you've got a good idea why you might wanna pick this up for your Mustang, let's look a little bit closer at how Performance Distributors achieves this, and put simply, guys, this thing just cranks up the spark out plug. Rated at 45,000 volts, the coil improves combustion by allowing the spark plug gaps to be opened larger than stock. Now that increase essentially exposes more electrifying voltage to the fuel mixture for a more consistent burn, which essentially equates to more power and more torque. So, like I said a little bit earlier, you're going to feel much stronger and better starts. And while I go on record saying that this isn't something that will fix a preexisting condition or problem with your car, we've had plenty of customers let us know that after installing this, that they experienced the much smoother idle, along with better throttle response and even, in some instances, better fuel consumption.In terms of the hardware though, folks, this little guy features brass terminals and it's epoxy-filled which just essentially means that it's gonna hold up to heat transfer or any types of vibrations caused by wherever you're gonna be driving. But when it comes time to pull the trigger, just like I said a little bit earlier, this isn't gonna hurt your wallet in the slightest and only expect to be spending about 100 bucks to get this on your car. Now, this is a really small price to pay to help your car work better, and if you're gonna pair this with plug wires and new plugs, like a lot of customers just doing back in the product page, it's gonna give you a night and day difference. Insulation-wise, you're looking at around an hour job, which warrants an easy one of the three wrenches on our difficulty meter here, only needing a pair of sockets.So, start with disconnecting the main connection to the ignition coil, and then disconnect the six spark plug leads. Using a socket, remove the four bolts, there's gonna be one on each corner and then pull that off. You can then get the Demon into position and make sure that it's snugly in the recess and that the main connector is facing towards the firewall of the back of your car. After that, using a 9/32nd socket, reattach the four corner bolts but don't forget the earthly needs to be added to the correct bolt. That's gonna be the one closest to the spark plug lead number five. Now, the unit mounts best if you leave all four bolts a little loose, and then try to wiggle the coil slightly down before tightening everything into place.So that's my quick review and breakdown in Performance Distributors Screamin' Demon Coil fitting the 2005 to 2010 V6 Mustang, that can be found right here at

    More Power. The Screamin Demon Coil Pack makes more power then the wimpy stock oem factory coils to improve throttle response and to produce more horsepower and torque from your Pony's 4.0L V6 motor.

    45,000 Volts. Screamin Demon's 6-tower style coil features a maximum of 45,000 Volts, that's more energy than the factory OEM coils can produce. More energy equals a hotter spark that burns fuel more completely releasing all it's potential energy translating into quicker starts, better fuel economy and more power that you can feel.

    Durable Construction. Built rugged, the Screamin' Demon Coil features brass terminals and is epoxy filled, providing improved heat transfer and vibration resistance for a long trouble free life.

    Application. The Screamin Demon Coil Pack is designed as a direct performance replacement upgrade for the 2005 to 2010 4.0L equipped V6 Mustangs. This Demon coil pack is perfect for stock and mildly modified engines.

    Is this coil good for upgrade? I am a first time mustang owner and going to do a full tune up, does this coil work for a performance upgrade. Any recommendations on spark plugs, wires, and anything else?


    • I did the Taylor wires, NGK Iridium and TB spacer from Steeda. They work well together. Good throttle responce and better MPG. Make sure to gap the plugs to .065 per Screamin's advice. Plugs are at .052 shipped.

    I put an SR performance strut tower brace on my V6...and I had to use washers to give it the height to clear the stock coil only 3/4 inch. Is this coil pack taller? I have no room to spare height-wise without hitting tower brace. Thank You.


    • This coil pack is going to be the same style of dimensions as the OE but produce a higher voltage, should not be any larger.

    how much hp is this going to increase


    • Upgrading the Distributor Coil will not increase your power. Upgrading will help your motor run more efficiently and smoother all around. Rather than increasing your power, it will be freeing up power where your car was restricted before do to a stock worn out Coil.

    I recently purchased the demon for my 05 v6 Stang I plan on reusing my recently purchased NGK V power nickle plugs and opening the gap to the 0.65 recommended setting is this ok with these plugs or should I not open them that much . I think they are currently at the factory settings of 0.52.


    • Yes, installation of the Performance Distributors Screamin Demon Coil allows you to open your spark plug gap to .065

    Just installed this along with the Taylor Street Thunder spark plug wires. I had multiple codes come up from my engine saying that my car is now running too lean. Do you know why it would be doing this? Is there something wrong with my fuel system?


    If I purchase the screamin demon coil, do I need to buy the spark plug wires too?


    • It is highly recommended to get spark plug wires at the same time as the coil but it is not necessary to perform an install with the screamin demon coil onto the vehicle.

      Great mod if you combine with other mods

      At first I was skeptical like others. I have a 2007 Mustang V6 4.0 project car that is being transformed. I have the dual exhaust and waiting for the rest of the intake parts and decided to take the plunge for the screamin demon and livewires and Iridium NGK plugs. Wow! It is a worth while modification. Without a tune yet it improved the Pypes exhaust note to be more throatier and less droney? That and noticeable difference in the low end and and nice and smooth idle and purr of the exhaust. You will notice this when combine with the wires and GOOD plugs and other mods. Ive got a tune waiting to program with this part of the tune so I can't wait to put in the throttle body and CAI and give her a tune to see what the whole package does. I can tell you I had them installed and it's gapped at .06 and it runs just fine. The first start up I think the computer was confused the idle was a little hesitant and I heard ping. After driving about 5 miles and few starts the computer apparantly learned. Sounds beautiful, runs nice with a noticeable improvement in gas mileage. Don't expect miracle supercharging here but it's worth dumping the cash if you add it with other mods it will be noticed and smoother running. Make sure you use dieelectric grease and anti-sieze grease. Failure to use the included grease with livewires will void the warranty! RECOMMENDED!

      Grea Product for the price

      Great product. install for the distributor took about 30min start to finish. nothing special or fancy about it. gives you a smoother idle, as well as a smoother take off and a noticeable gain in MPG. keep in mind that when you remove the old distributor, there is some sort of sensor that is grounded with one of the bolts, dont forget to re connect that or you will probably get a check engine light. i recommend this product.

      Easy upgrade to improve from idle to overtaking

      After reading some reviews I thought this would be a small improvement but I was very pleasantly surprised... I got the coil along with recommended Taylor Street Thunder plug leads and the NGK IX plugs (gapped to 0.065"). Installation was quick and easy (with the caveat on the V6 that a couple of the spark plugs are a pain to get out - I did get a helping hand from someone who's done it before!) and the difference was obvious as soon as I turned the key... Idle is much smoother, certainly no chance of mistaking my Pony for an F-150 now ;) and it continue to impress through the rev range especially the 40-60mph over taking on country roads... so much smoother and more willing to get up and go. I have a CAI and tune on the car but this has really helped bring out the fun (now I need to fix the handling!)

      This product takes about 30 minutes to install, make sure you line up each spark plug wire to the cylinder number. Make sure you upgrade the spark plug wire to, for a nice difference. Engine really reacts.

      SD Coil & NGK Plugs

      I purchased the SD coil and NGK Iridium IX spark plugs. I also purchased the Livewires from a different vendor. The motorcraft OEM coil is almost identical to the SD coil. My stang was inserious need for spark plugs so the new NGK were a blessing. As far as the wires, they seem to be about the same to the motorcraft OEM ones. I measured the width and came to the same diameter. My mods include a JLT CAI and SCT performance tune. The installation does not require any major mechanical knowledge. It is easy by comparison, but takes time since you have to work in tight spaces removing the spark plugs. After the installation and maiden trip and can honestly say I didn't notice a faster startup. I did notice a faster pickup/accel. As far as MPG, I cant really tell, but I hope is better than the stock coil.

      Crisp throttle response, improved mpg

      Easy to install, this gives excellent throttle response. It feel like what it 'should' be. Put on my 2006 with about 114k miles complements new wires and sparkplugs at 100k. In mixed driving (city/hwy) this has given a solid 2mpg boost and I haven't re-gapped my sparkplugs yet!

      Nice engine upgrade

      I recieved my new coil yesterday and installed it. Total installation time was about ten minutes. My '06 Mustang has about 114K miles on it so this part was both for engine maintainance and a performance upgrade. On the low end my engine idles much smoother. On the top end acceleration is improved dramatically. Nice upgrade at a great price!

      The way I see it is...

      The Screamin' Demon fits perfectly in the OEM placement, doesn't increase performance but does feel like it's getting every last bit of the injected gas. There was an immediate change in the sound of the car after installation, which only took ten minutes plus two minutes to un-crosstwo of the wires. The only complaint I have is that the supplied rubber electrical boot ring was too big and kept getting squished in the connection, so we used the original which was fine. Overall 8/10
