    Hey guys. Stephanie with 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

    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.

        I have the original stock coils in my 2000 4.6L Mustang GT. Lets say if I wear yo buy this coils would I need to do some tuning in my car or can I just install them without have to worry about tuning my coils are bad I just want to add some good quality part in my engine so it can always run good and healthy also are this street legal will this give me problem with the emissions test if so can you recommended me something good and legal please and thank you?

        • You can install these without having to upgrade anything else as these are a direct replacement for the OEM coils. You will not need to get a tune for these either and this is legal to run and would help with performance due to the current ones you have going bad.

        will I need to have bama send me a retune if I change out coil and plugs?

        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 !!

        • Hello! Unfortunately the SR Performance Coil On Plug Kit is only sold as a set of 8.

            Works Perfectly

            I have a 2000 Mustang GT with 155k miles. My "check engine soon" light came on. I still drove it around, but knew I had a tune-up problem since I was experiencing a loss of power. Soon enough, when I accelerated a little hard, the loss of power would worsen and the "check engine soon" light would flash. I changed my spark plugs, PCV valve, EGR valve, cleaned my throttle body, and changed my air intake. I purchased a $100 OBDII bluetooth scan tool and it said I had a misfire in cylinder 1, code P0301. So after I looked around for the best price and reviews, I purchased these SR Performance Coils and installed them, and instantly the car felt like brand new again and the check engine light disappeared. The hesitation in acceleration has vanished. What a huge relief!!!

            Coil Packs

            Purchased these to replace my stock ones that went bad. These work exactly like they should. The car ran much smoother with these in it. I could also notice a small increase in power. The car feels much more solid now. I would definitely recommend these to any 2v owner.

            SR coils

            They worked great but after a year they failed and made me misfire horribly. Consider this as only a temp fix if you cant afford more expensive brand longer lasting brand or even stock ones

            had a miss in one of the cylinders and replaced the bad one and it fixed the problem. my only complaint is that they dont come individually. i only needed to replace one but i had to buy eight of them.

            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.

            Short life

            Bought these about year and a half ago. Worked awesome at first. My 03 gt started hesitating and rough starts about two weeks ago. After pulling plugs and finding all in good shape I started to disconnect one COP at a time. Found that 3 and 5 disconnected made no difference in how the car was running. Called AM and these things only have a 90day warranty. Can't buy singles. Decided to get others. Wouldn't recommend these due to short lifespan!
