Keeping the naturally aspirated 3.4-litre MA1.23 flat-six operating at peak efficiency requires strict maintenance intervals. Whether you are daily driving a Boxster S or attacking apexes in a Cayman GTS, running fresh Engine Fluids is non-negotiable for a healthy 7,800 rpm redline. We stock complete Service Kits to make oil changes straightforward. Swap out aging Service Filters to maintain clean airflow and lubrication, and install a fresh set of Spark Plugs to guarantee consistent ignition timing across the entire rev range.
