Oil coolers are an important addition to any high performance engine which gets works hard. Engines which are constantly revved high can easily overheat the oil which then becomes thinner and offers less protection, resulting in premature engine wear.These pressed plate type of oil cooler radiators are very popular and have been fitted to performance road and race bikes/cars for many years and are available in a huge range of sizes to suit all engine types.Oil Cooler FittingThe coolers are fitted in a position where airflow can pass through them (usually at the front of the bike/car, by the radiator) as it is this airflow which cools the oil as it flows through the oilways within the cooler. Oil is supplied to the cooler by pipes which connect to the engine, usually via a sandwich plate which fits between the engine and the oil filter.Oil Cooler SizingThe Mocal Oil coolers are available in 2 different matrix widths 115mm and 235mm. The overall width including the brackets is 210mm and
