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 americanmuscle.com.
