Audi RS3 8V Spark Plugs

The Audi RS3 8V is split up into two versions. Pre and Post facelift with very different ignition systems. You must be careful to match your engine code to the right product. 

Pre facelift uses R8 ignition coils and its own specific spark plugs (CZGA/CZGB). The facelift uses the same coils and spark plugs as the MQB platform and you might want to also look at NGK racing spark plus for high boosted DAZA/DNWA applications.
