Poor idle, low fuel efficiency, and engine misfire codes are all symptoms of worn spark plugs. Over the years, the electrode wears away on spark plugs, causing too large of a gap and weak spark. Additionally, excess carbon can build up and bridge the gap to negatively effect performance. Replace yours with these units to regain your power, fuel efficiency, and smooth a poor idle.
-Specifically for APR Stage III turbo kit cars in all 1.8T applications. These plugs are one heat range colder than OE, this helps prevent pre-ignition and other misfiring issues that may be caused by the increased level of fuel/compression in chip tuned vehicles.
If you are replacing any aspect of your ignition system, it's best to replace all serviceable components. By doing so, your ignition system will work in better harmony, freeing up hidden horsepower and raising fuel economy. Skim the ECS Tuning ignition area under your model for coil packs and more to get your vehicle into top shape.
