Product Description

Set of Four MSD Iridium Spark Plugs with a 12mm Thread Size for 2008, 2009 and 2010 GT Mustangs.

MSD has made it easier to get more power out of your ignition system without making major modifications. Your 2008-2010 GT Mustang with 4.6L engine will reach max power thanks to these 12mm MSD Iridium Spark Plugs 37174 from CJ Pony Parts. Crafted with a zinc-nickel coating, these performance spark plugs will outlast every other copper plug on the market and never corrode. The Iridium contact will improve your ignition system's efficiency while promoting the best combustion event, all making your ignition system more powerful.

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
- Easy direct-fit installation
- 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
- Engineered to improve the efficiency of the ignition system to create the most power possible

MSD has created the best possible spark plug for your modified Mustang GT'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.

*If you have a 2008 Mustang, you need to determine if you have 2005-2008 "high thread" 16mm spark plugs or 2008-2010 12mm spark plugs. This can be determined by looking at the coil engineering number. If you have a 3L3E number, you have 16mm spark plugs (MSD37164), if you have an 8L3E coil engineering number then use the 12mm version (MSD37174).

Please Note: Two sets of these 12mm MSD Iridium Spark Plugs will be needed for 2008-2010 GT Mustangs.

Order a Set of Four MSD 37174 Iridium Spark Plugs with a 12mm Thread Size for your 2008, 2009 or 2010 GT Mustang from CJ Pony Parts today!

These are sold as a set of 4 and provide a hotter spark than the factory plugs, and will be a direct replacement with no modifications necessary. They come ready to install, and will last longer than a conventional plug. These plugs again are sold as a set of 4. Make sure you order 2 sets for your V8 Mustang.
