Your modified 2003-2004 Cobra and 2007-2012 GT500 engines will thank you for this upgrade!

MSD Iridium Spark Plug Features and Benefits:
- Set includes four individual spark plugs
- Plugs are machined to expose more spark to the incoming gases, which promotes the most effective combustion event
- Engineered to improve the efficiency of the ignition system to create the most power possible
- Engineered and designed specifically for use on performance engines
- MSD's Iridium Spark Plugs last longer than an average copper plug
- Zinc-Nickel coated shell resists corrosion
- Easy direct-fit installation

MSD has created the best possible spark plug for your late-model Mustang's ignition system. These performance spark plugs are engineered to improve the efficiency of the combustion process to create more power combined with increased durability. The center tip of these plugs are made from iridium to promote the best spark and increase resilience.

MSD's proprietary ceramic material enhances the dielectric strength of the plug housing, forcing the spark to jump across the plug gap to the ground electrode. This electrode is machined to expose more spark to the incoming gases to promote the most effective combustion event possible.

Please Note: Two sets of these spark plugs will be needed for Mustang Cobra and Mustang GT500 engines.

Order a Set of Four 37144 MSD Iridium Spark Plugs for your 2003-2004 Cobra Mustang or 2007, 2008, 2009, 2010, 2011 or 2012 Shelby GT500 Mustang from CJ Pony Parts today!

MSD Spark Plug Iridium Set Cobra 2003-2004/GT500 2007-2012 Video Transcript
By Bill Tumas: We’re here with a set of MSD's Iridium spark plugs fitting your 2003 through 2004 Cobra, and your 2007 through 2012 GT500. These MSD Iridium spark plugs are the perfect choice for your factory supercharged Ford Mustang. They'll be a direct replacement for the factory plugs, and provide a hotter spark and much higher performance, and work great at higher boosted levels. These are sold as a set of four, so you will need two sets for your V8 Mustang. These will be direct replacements, again, for the factory plugs, will work with factory wires, and will outlast your typical copper plug. These Iridium-style spark plugs come pre-gapped and ready to install, are not designed to be used with a typical style gapping tool.
