CSF Radiators BMW E46 M3 Race Spec Dual pass Oil Cooler is an essential cooling modification for improved reliability and increased performance, especially on track. With a perfect 'drop-in' fitment for the E46 M3, this oil cooler from CSF was developed in partnership with Rogue Engineering - a high-profile BMW tuning specialist - to ensure maximum cooling.

Why are high oil temperatures bad?

When oil overheats, it deteriorates at a much higher rate. This reduces the oil's ability to effectively lubricate vital engine components which puts the E46's S54 at extreme risk of internal damage.
