Mishimoto LS Ignition Coils Square Style (Set of 8) for 1999-2007 GM Truck (Silverado/Sierra)
The basic requirements for a properly running engine are fuel, air, compression, and spark. Before increasing the power of your LS engine, it's wise to ensure all maintenance is up to date and these processes are performing as intended. Weak spark from your ignition system can result in misfiring, rough idling, poor gas mileage, and damage to your catalytic converter; all of which hinder performance.
Mishimoto is proud to launch their new lineup of ignition coils, aimed at providing high-quality replacements that can bring your vehicle up to Stage 0 before moving on to horsepower adding modifications. Their ignition coils are designed and tested to meet or exceed OEM GM performance standards and are available as a single coil or in a set of 8. Once installed with a set of new spark plugs, one can expect a refreshed ignition system with improved engine startup, a smoother idle, and restored performance from your LS. Mishimoto ignition coils are an ideal replacement for worn or defective factory coils.
