Hey, guys. Stephanie with here with the MSD Blaster Coil-on-Plug Set for the '99 to 2004 GT Mustang. The MSD Blaster Coil-on-Plug Set's gonna be a good option for those two-valve owners out there that are looking at a little bit of a stronger spark to tie together and make the most of some existing bolt-on mods and improve fuel economy as well. Upgrading your coil-on-plug setup's gonna give you a hotter spark, which is gonna have some performance and fuel economy benefits. Even if you aren't necessarily specifically looking for a hotter spark, if you're shopping for coil-on-plug kits, you're looking for a stronger spark, or you're just looking to replace some worn-out coils. At the end of the day, a hotter spark is a stronger spark, and this has a lot to do with the voltage of the coil-on-plug setup. The performance gains of an aftermarket coil-on-plug kit, like the MSD here, are derived from the coil utilizing the hotter spark to create a more complete combustion of the gases in the chamber. The MSD coils are able to do this through a longer than factory firing time. The longer firing time is possible through the higher voltage that the coils have. Aftermarket coil-on-plug kits have a stronger voltage than the factory components, which is where the improvements over the factory's going to come from. A higher voltage allows for a longer firing time, because a higher voltage has the ability to allow the spark plug to jump a larger gap. Even the lightly modified or completely stock Mustang can benefit from upgrading to higher output ignition coils, and this all comes back to the difference in voltage output between the MSD coils and your factory coils that I just explained. Ultimately, if you want a hotter spark, then upgrading your coil-on-plug set is about the only way to go. So creating more complete combustion creates some benefits, like increased fuel economy, improved idle quality, better throttle response, and even a touch more power, since the air and fuel are burning more completely and releasing all of the potential energy. One of the main things that you can expect is better acceleration with this coil-on-plug set. It's not gonna be a huge difference, but a noticeable one for sure. I wouldn't say that this is a mod you'd do to gain more power, but when you do, to allow more power and a cleaner burning setup. This isn't like changing a pulley setup on a blown car, but it's more of a bolt-on that would give you better drivability. Another thing to keep in mind, even though it's a secondary thought, but these are going to be noticeable under the hood. They're the iconic MSD bright red, and they give an aftermarket look to the engine. But if you hate the red and aren't really a stickler for the brand, there are a ton of coil-on-plug options out there, and yes, there are different colors as well, and of course, different price ranges, too. And speaking of price, the Blaster Coil-on-Plug Set's gonna be one of the more affordable sets, costing just under $200. This is less than most of the other options out there, but it's not the least expensive set out there either. So if you're looking to spend a little less, you can check out the SR Performance kit. The install here is not difficult at all. It's a one-wrench install and should take about a half-hour to complete. You're gonna want to disconnect your battery and have some dielectric grease as well, but the actual install is as simple as disconnecting the coil connector, removing the coil retaining bolt, and pulling the coil out for each cylinder. The new MSD coil installs the same way over the spark plug. The boot slides over the plug and fits right into place. The retaining bolt goes right back in, and you plug in the connector. One thing to consider is changing your spark plugs while you're in the area. It may lengthen the install time, but it's only going to help things. So wrapping things up here, the MSD Blaster Coil-on-Plug Set is a fast and easily installed way to gain some performance benefits from a hotter spark. You're gonna expect some improvements in drivability, acceleration, and fuel economy as well. The work if you need to do some maintenance and replace your coils or if you're looking to upgrade your ignition setup to help support some mods, you can check them out more online right here at

More Horsepower. The MSD Blaster Coil On Plugs make more power then the wimpy stock oem factory coils to help produce more horsepower from your modern SOHC modular motor and are a perfect match for stock engines and engines with minor performance upgrades.

Better Fuel Economy. The MSD Blaster Coil On Plugs produce a hotter spark that burns fuel more completely releasing all it's potential energy translating into better fuel economy and more power.

Application. These MSD two valve Blaster Coil On Plugs are designed as a direct performance replacement for the 1999 to 2004 SOHC GT Mustangs.

What is the voltage on these?O someone already asked, but the answer is unclear. Is it 25000 more than the 20000 stock making it 45000? Or is it just 5000 more making it 25000?

Will these work well with a 93 octane tune? Wondering if these will work better than OEM coils running a 93 octane time on the car.


  • These will work better in general no matter what tune you have.

    Woke up my stang

    I have 143,000 miles on my stang and for the longest time I've been hunting down a low rumble/vibration on acceleration and deceleration. Over the years I've checked for exhaust binding, wiring issues, differential issues, harmonic balancer, spark plugs, and computer codes. The car has always run ok, but never really felt strong like I thought it should. Even though my PCM didn't throw any codes, it just seemed like the car might be misfiring even though everything checked out.. The car almost seemed to die at idle sometimes at random. Yeah, I replaced my IAC too. So I figured it wouldn't hurt to replace them, particularly on sale So finally long story short, these coils made a HUGE difference. Now I have to relearn the clutch because it wants to break traction. It feels more powerful and is quieter cruising and idling too. The exhaust note got deeper as well. For those comparing to stock, the build quality is as good. The weight is exactly the same as stock within 1 gram. Of course, MSD makes no claims other than they some internal differences to increase output. From my experience, I believe them. I thought about the Accel but I've had mixed results. So far MSD has not let me down. If they do, I'll update my review. Until them, I'm one happy camper.

    Good Sense

    Installed these along with the NGK iridiums on my 01' GT and couldn't be happier. Not knly do I know they are a good product that is getting me a more powerful and efficient spark, I can feel and hear it in the revving and idle - cold starts are nice and crisp. Before I did the switch the engine would turn over but fail to start here and there, but now I haven't had a problem with that. Pushing 80k miles on my GT and she's back to starting nice and tight.

    Good Packs

    Hard to say much about power gain, because they were done with a host of other bolt on mods. I can say install was simple and they are a great looking quality made product. I would expect nothing less from MSD. Throttle response is great, and with all the other bolt ons, is a totally different motor. Just need to throw a tune on it to get the full potential. Would highly recommend this product.

    overall a good product. I've been running this coil packs for about two weeks now and no problems. Install was simple and gas mileage has noticeably increased. Hothrottle response was only minimally affected in a positive way. Horsepower increase hard to guage because i have many other bolt ons. Dyno would probably be more conclusive.

    Awesome Product!

    As part of a host of other performance bolt-ons (plenum, plenum spacer, throttle body, cat-back exhaust, & underdrive pullys), I went for this product after reading all the American Muscle reviews on the other coil sets. Excellent price, quality construction, easy installation, and flawless performance. At approximately one-third the cost of a dealership set, this one's a no-brainer!

    Good Buy

    My Mustang had 125,000 miles on it, so I decided it was time to do a little tune up. I installed these with a set of NGK Iridium plugs (first plug swap too). Install is easy. You do not need to remove the fuel rails to do this. The rubber part of the coils is very flexible, so you can bend them in and out with ease. I noticed a smoother idle and some better fuel mileage, but not so much on performance. There's a little, but it's nothing staggering. I'm just happy that my car is running smoother with better mileage now!

    Love it.

    Can't begin to describe how easy it is to install this product, I have little to no experience with cars but am quickly reading and learning everything I can, this job, along with the iridium spark plugs on here took me 45 minutes to install and was as straight forward as can be. They took less time to ship! The power gain was little to none at first, after about 200 miles of driving... cops wouldn't call it that, I noticed a very noticeable response from my pony's pedal that was missing before. Thank you for everything you offer American Muscle. I'll be doing much more business with you all in the future.

    Like others have commented, I didn't notice any big performance gains, but the old stock coils (and a few knock off replacements) must have been failing. After replacing with the MSD coils, no missing and runs like a top with 150K miles.

    Great Power Upgrade, Well Worth It !!!

    I purchased these, as well as matching MSD plugs, to replace the factory plugs in my new (to me!!) 2002 GT Convertible with 12,500 ORIGINAL MILES !!! Old plugs weren't too bad, but I NEED MORE POWER !!! Paired with these coils, WOW !!, immediately noticeable throttle response. Airaid cold air intake (Dry), MSD plugs and coil packs, and a BAMA inTune I2 tuner, this AUTOMATIC launches you into your seat, AND chirps the first 2 gears !! Love it !! Pretty easy install, I have VERY limited mechanical experience and I completed this in about 2 1/2 - 3 hours ( lost a socket in fender well, SET-BACK) !! Tip: DO NOT REMOVE ANY FUEL RAILS, these will wiggle into place and cap in with enough pressure, especially once the bolt is secured down snug.

    MSD Blaster COPS on a Bullitt

    I installed these on my 2001 Bullitt. I had the original Ford COPS up to this point. Install required removing the C.A.I. and a couple of other brackets to allow for easy access. I would advise removing these items rather than trying to work around them as I dropped a COP bolt and had to go hunt one down at the parts store since I never could find it. I also removed approximately 1/4 inch from the boot as my original springs were closer to the outer lip than these were and I didn't want to have to backtrack to fix issues. Car runs great and I love the red accents I now have under the hood.
