Complete Oil Change Kit Mid-Engine Flat-Six 9A1 (2.7, 2.9, 3.4) – Liqui Moly Leichtlauf High Tech 5W-40

Oil is the lifeblood of the engine. In this mid-engine 9A1 flat-six, it protects moving parts from wear, dissipates heat and retains combustion residues. Over time and with increasing mileage, it loses these properties.

Why a 5W-40 Porsche A40? This is the standard required by the manufacturer for this engine. The A40 standard requires very high shear resistance: at high temperatures and high speeds, the oil maintains a thick, stable film, exactly what this engine needs.

The filter. On this engine, the filter is a cartridge: only the filter element and its seal are replaced, while the housing remains in place. Geha Performance has selected the MANN-FILTER HU 7026 z cartridge from a renowned German manufacturer, supplied with a new seal. It replaces the original part 9A1.107.224.00 / 0PB 115 466 A.

The drain plug washer. The plug is made of metal and can be reused. Its aluminum sealing washer must be replaced at every oil change: the kit contains a new washer with the same dimensions as the original part 900.123.106.30.
