Every 60-80,000 miles, we recommend replacing your spark plugs and coils to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, we have put together our High-Performance Ignition Service Kits, now featuring our very own Turner Performance Ignition Coils! These kits include our new Turner Performance Ignition Coils, new OEM Bosch Platinum+4 spark plugs, and AGS dielectric grease. The new Turner Performance Ignition Coils are designed with performance and efficiency in mind. An engine needs 3 main components to run (Air, Fuel, and Spark.) Ignition coils are responsible for 1/3 of the operation of your engine and it would be smart to weigh the options when shopping. Turner ignition coils are modified to increase energy output; more energy output results in a faster, more efficient, and consistent burn to make sure your fuel is being utilized to its maximum potential.
