Keeping the BMW E92 M3 Cool With CSF Radiators

,

The stock cooler on top is pretty big but judging from the super high oil temperatures, not nearly big enough! The CSF cooler is both thicker and taller with superior fin design.  It should have nearly twice the cooling capacity as stock.
The CSF cooler was a squeeze to fit but bolted right in place. No shroud cutting was needed.
The CSF oil cooler is so big it looks like a front mount intercooler!
Pure Performance had welded these bosses into the stock oil lines beforehand so we could monitor oil temperature for the test.
The CSF radiator drops right in and bolts right up to the stock core support.
The CSF radiator is much thicker but it all fits and is direct bolt in easy!
