I've installed them on about 2 dozen race cars, they seem to keep the oil dead on 180. All were paired to a Setrab cooler. Usually huge for the engine size. Several on dry sump engines with Mocal filters. Good products. Dave __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black |
