      Description

      Regular Maintenance. Replacing your old weak spark plugs is paramount to keep your engine running smoothly and efficiently, so why replace them with the same old sub-par stock plugs when high performance plugs from NGK will improve fuel efficiency and lower your emissions.

      Superior Construction. NGK Laser Iridium Performance Spark Plugs feature an iridium disk that is welded on the center electrode and a platinum disk that is welded on the ground electrode to reduce the wear rate of both surfaces ensuring greater durability and longer life. NGK uses pinpoint precision laser welds to reduce excess debris decreasing the required voltage to bridge the spark gap for a more efficient burn.

      Application. This set of eight (8) NGK Laser Iridium Performance Spark Plugs are specifically designed as a direct fit replacement for the 2003 to 2004 SVT Cobra and the 2007 to 2014 Shelby GT500 Mustang equipped with the supercharged 5.4 liter V8.
