Proper maintenance of the 3.8-litre MA1.03 flat-six engine found in the 981 Cayman GT4 and 981 Spyder requires strict adherence to servicing schedules. These models, utilising the robust 981 chassis, demand high-specification Engine Fluids to protect their internal components during both daily driving and track use. We supply complete Service Kits that simplify routine maintenance. Regular replacement of Service Filters is essential to ensure optimal airflow and oil cleanliness, whilst fresh Spark Plugs are necessary to maintain precise ignition timing in this high-revving naturally aspirated engine.
