Hey guys. Stephanie with AmericanMuscle.com here checking out a little upgrade in the spark category for the two and three valve Mustang's which are SR Performance Shock Coil On Plug Kits for all GT's in the 1999 to 2010 range. SR Performance is a name that every Mustang owner should be very familiar with by now thanks in part to the wide selection of performance and suspension components for your Mustang with prices that aren't going to break the bank. If you'd like to check out more from SR Performance for your Mustang you can always head back to the website and check out SR Performance under the featured brand section of the homepage. So we just talked about SR Performance producing performance parts for your Mustang and in this case SR Performance is looking to add more punch behind your Mustang spark by making it hotter. If you want a hotter spark then upgrading your coil and plug set up is about the only way to go and even if you aren't specifically looking for a hotter spark ultimately at the end of the day your coils are an item that you might end up having to replace anyway so if you can squeeze a little bit more performance out of them then why not go for it? More complete combustion creates 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 the potential energy. This also means better drive-ability. Not only does this SR Performance kit offer more complete combustion, but it allows the combustion to occur more quickly which means that the current combination will be encouraged to make more power. Getting away from the more technical side of things let's talk about the install. This is a one wrench install and should take an hour or less to complete and it's pretty straightforward. There is an install guide on the product page for your reference and if any of your questions are not answered or you still have some concerns, you can always reach out to a Mustang expert for assistance. And guys if you still have doubts about the improvements that this kit can offer you, just take a peek at some of the customer reviews that are on the product page. If you need to do some maintenance and replace your coils or if you're simply looking for a hotter spark for your two or three valve, then you need to check out this shock coil and plug kit from SR Performance for 99 to 2010 GT's, available right here at AmericanMuscle.com.

More Horsepower and Torque. SR Performance 24,000 volt coils provide 4,000 more volts then the wimpy factory coils to help produce more power and torque out of your SOHC modular motor. SR Performance Coil Packs are the perfect replacement upgrade for stock engines or Mustangs with minor performance upgrades.

Better Fuel Economy. A hotter spark burns the air/fuel mixture more completely releasing all of it's potential energy which translates into better fuel economy and more power that you can feel in the seat of your pants.

Complete Kit. The SR Performance Coil On Plug Kit comes complete and includes all hardware necessary for installation including the 8 coil packs, connector cables, and stainless snap lock plug connectors.

Application. This SR Performance Coil On Plug Kit is designed as a direct fit performance upgrade for the 1999-2004 GT and Bullit Mustangs equipped with the SOHC 2-valve 4.6L Modular V8 engine.

How can I get just one coil pack ? Had one go bad and had to replace with a regular motorcraft one. So now I have 7 SR performance coil on plugs and 1 motorcraft. Is this hurting anything ? I did have to adjust my idle when I put the 1 mototrcraft in. Would like to have all 8 the same !!

    I bought these and I actually noticed they were not as powerful as the stock Motorcraft coils. I almost immediately noticed I lost power on top end. I would recommend just spending the extra cash and buying either ACCEL OR MSD COILS.

    Cheap, easy, and worth it!

    I had just bought my GT 3 months ago and had a 7th cylinder misfiring. I figured since I wasn't sure about the other coils I had I decided to buy this pack and replace all of them together. Not only did it solve misfiring issue, but It also added a little edge to the acceleration. Not a very noticeable power difference. But you can definately tell the extra voltage is just what your GT needed for that smooth ignition

    fast, simple replacement

    Cheap replacement for my bad coils. They seemed to weigh just as much as the stock ones. Didnt notice any power gains however but really can anyone notice a couple horsepower difference? Took less than an hour to put on.

    Would not buy

    When i read the reviews i decided on this set of plugs due to the affordability of product. I purchased the plugs and installed them on my car at 76.XXX miles, however looking back i should have made a different choice. My GT is currently at 78.XXX and one of the plugs is already broken . Really disappointed in the product as it is not the first SR part that has failed me with very little actual drive time after installation.

    Easy fix for my misfire

    I had a Cylinder 5 misfire on my '03 GT, and new spark plugs did nothing. I got these bad boys and they fixed it immediately. Also noticed an increase in acceleration, well worth it!!

    No noticeable gains

    My 02 GT is close the the 100k mile mark and still had the original cool plugs. This is usually the time you would want to replace them even if your not having a problem. I seen these SR coils and read some reviews, everyone said that they seen immediate power gains. I figured for the price I would get them. Unfortunately I did not see any gains at all. The only reason I recommend this product is the price.

    I had misfire in cylinder 7. COPs were the original since the car rolled off the factory. Good set of coils, they gave my car a smooth power gain and the misfire is gone.

    Immediate improvement

    I replaced my coils along with the plugs as part of my maintenance which was sped up by a misfire and I couldn't be happier with these plugs. It took a little while for me as I'd never replaced coils/plugs on a mustang before and had to remove the fuel rail and replace the fuel balancing hose since it was brittle, but it was very straight forward. Pop old one's off and pop new one's on. Immediately cleared my misfire with a great startup and have noticed my fuel efficiency has gone up along with the throttle response. Clean all across the board!

    Results where as expected

    This product is pretty much as advertised , my 2001 gt seems to run better through out the mid range rpms,but I also have installed ngk plugs as well . But it definetly performs better on the nos since I installed the coils and plugs and changed the gap

    SR Performance Shock Coil On Plug Kit (99-04 GT)

    Easy install, did notice better than sight gain in performance, mostly seems to be in the mid to high rpm range. With the only engine mod being the SR cold air system, was not expecting a whole lot, I have an 02 GT with 128K miles, and still had the factory coils, was very happy after the install. Highly recomend

    Pleased

    I ordered these cops because of the price. I had a small engine tick for years that went away after installing these replacements. It has been six months and so far these are at least as good as the oem coils.
