2011-2014 Mustang GT Ignition System Upgrades

Sort by:

The 2011-2014 Mustang GT uses an advanced coil on plug type of ignition system that has proven to be reliable and efficient on modern high horsepower production cars.  As a manufacturer of the industry's highest quality automotive electronics, JMS understands how proper spark capacity and voltage play an integral role in fuel and engine performance.

JMS has performed extensive studies and spent countless hours testing the current Ford ignition systems, especially on the newer Mustang GT and Shelby GT500.  We have built numerous 500-750+ horsepower Mustangs, and many, have suffered from ignition related issues that only computer ECU custom tuning could adjust for.  Our PowerMAX SparkMAX Ignition System Voltage Booster was engineered specifically for these types of vehicles, and transcends far beyond common-brand ignition boxes.  SparkMAX offers the cleanest and highest voltage of any type product on the market, and it has the least amount of voltage fluctuation at almost 0%.


The JMS PowerMAX SparkMAX Ignition System Voltage Booster for 2011-2014 Mustang GT is an exclusive product that was designed just for you and our other customers.  In the development process on the newer 5.0L Coyote engine, as well as in the past with the 4.6L, 5.4L and 5.8L supercharged engines, we had cars that made well over 800 RWHP that would not rev past 3,500 RPM and would completely run out of spark regardless of how tight the spark plugs were gapped.  SparkMAX was designed to solve that problem, and also open the door for more correct engine calibrations with better fuel atomization, and measurable improvements in horsepower.  It also allows you to experiment with wider plug gaps for better fuel burn and economy.


When it comes to the ignition system in your 2011-2014 Mustang GT, you can put your trust in JMS and the best engineered, most extensively tested products on the market.
