      Review & Installation Video

      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

        Not reliable !!

        So I installed the SR performance coils and at first everything was good . No issues . Mind you I installed these as an upgrade. No other reason . Long story short I’ve thrown away 2 already for what I consider premature failure. Thankfully I kept the stock ones I removed and keep 1 in the car at all times just in case . Buyer beware...

      Are these labeled to be put in specific firing order or does it not matter which they go ?

      • It doesn't matter in what order they are installed, just make sure that they are facing the same direction as the coil on plugs you are replacing and you will be set!
