Review & Install Video

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.

Fitment: 1999 2000 2001 2002 2003 2004 Details

    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.

    30 mins.

    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.

    STOCKS ARE BETTER

    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.

    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

    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

    Great coil! Great price!

    SR. Performance coils are perfect for a daily driver with moderate modifications. They work great in my 2000 GT. They are a great value.

    Great replacement

    My 04 GT was not starting well. It would start then die, and sometimes be hard to restart. I had no codes coming up. I figured my stock coils are 10 yrs old so I decided to start here. Wow, I hit the key now and vroom! I recently did a H pipe and Bama tune so I don't know about actual hp gains, but I know I have a good strong spark now.

    Great Coils

    Needed a tune up for my 02 GT 5 speed 90k miles. Put these coils in and now my car is sounding great, has more power and is getting better gas milage. I also put in new Bosch sparkplugs with these coils.
