AIRTEC Motorsport Oil Cooler for BMW E9x M3

Designed for the BMW E90, E92 and E93 M3, the AIRTEC Motorsport Oil Cooler is a direct replacement unit featuring a core that is 79% bigger than the standard BMW unit, together with an increased frontal area of 17% over standard for improved air flow and significantly greater cooling capacity.

Track-tested back-to-back at the Nürburgring, the AIRTEC Motorsport cooler demonstrated a 205% improvement in temperature reduction over the standard oil cooler — delivering outlet temperatures of 76°C versus 110°C with the original unit under identical conditions. On average, the AIRTEC cooler removed double the heat of the standard item.
