Mishimoto 09-13 Audi A3 2.0L Ignition Coil turn14-in-stock as well as silicone hoseManufacturer Part # : MMIG A3 09 Market Description The basic requirements for a properly running engine are fuel, air, compression, and spark. Before increasing your engine's power, it's wise to ensure all maintenance is up to date and these processes are performing as intended. A 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.
