Easily lower your engines operating temperature for maximum driving performance!!

135 335 535 N54 and N55 Motors

Maintaining higher oil temperatures reduces emissions at the factory power levels but puts your engine cooling at a serious disadvantage at higher power levels. This simple device lowers your oil temperatures by bypassing the factory oil cooling thermostat and allowing oil to circulate through your oil cooler full time. The result is dramatically lower oil temperatures and more consistent engine performance. Engine oil warm-up time is only marginally increased. Installs in minutes and is fully reversible.

BMS Oil Tstat

This simple device did wonders to my oil temperature at the track, even with higher boost levels while using a more aggressive Cobb Tune OTS Map. I never passed a notch below the half way mark on my N55 (235*F / 115*C)! (Sep 09 2014, 03:46 AM)
