The Mazda RX-8 Oil Pump is provided to supply pressurized lubricant that keeps the rotary engine cool, quiet and revving. The meshing gears of the unit drive about ten psi for every one thousand RPM into bearings and rotors by pulling oil out of the sump through a fine strainer, cutting friction and blasting off heat. With a long track record of reliability, this robust hardware has been popularly known to operate all three forms of factory drive, direct, gear and chain drives, with heavy-duty housings, tight clearances and a spring-loaded relief valve to protect seals during high revolutions. Its high-quality materials are based on Mazda factory standards, thus its owners have confidence in it. No matter whether your Mazda coupe has the early 2004 chassis or the face-lifted 2009 model, the Oil Pump still uses the same pump bolts as a direct fit, which is why it is a cross-generation fit to all RX-8 models that were made between 2003 and 2012. The optional high-volume Oil Pump is popular with track fans who enlarge bearing clearances with extreme loads, but just about any user benefits as much since the pressure at the starting point remains constant and hot-spot failures are avoided. The regular lubrication also increases efficiency, as reduced drag allows the twin rotors to spin freely, and it also increases safety, as there is less risk of sudden seizure when spirited around corners. A rapid check window allows the owner to inspect relief valve travel, and the design is mounted on the crank, which allows the weight to be kept as close to the centerline as possible to maintain almost flawless balance. The location of the Oil Pump low in the block allows the RX-8 to have a low centre of gravity. These Oil Pumps should last far beyond 100,000 miles when fitted with a new gasket, and they do not lose specified pressure, allowing any Mazda rotary to continue to hum past 9,000 rpm.
