Description

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

Product Overview
