I am going to put new Spark plugs in my 1989 964. Is their a new update plugs that we can use or do I stay with Bosch FR5 DTC. Thanks Vernon

Stay with the Bosch factory plug. 20 years of 964 street and track driving experience allows me to suggest that those plugs don't need to be changed very often and do not limit the engine/ignition's performance.
