The basic requirements for a properly running engine are fuel, air, compression, and spark. Before increasing the power of your 4-Cylinder or V6, it is 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 under high load driving and spark blow-out, which hinders performance. -- Mishimoto is proud to launch our 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.
