CSF BMW M3 Race Spec Dual Pass Oil Cooler (E46)

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.
