High Volume Oil Pump

Oil delivery is very important in all engines...available as an alternative to the stock 45psi oil pump is the choice of a high volume oil pump, which will deliver around 40psi at idle instead of the 6 psi the stock oil pump delivers at idle. When operating at slow speeds for long periods of time (excessive idlers, stop and go driving), engine parts are being worn more then when the engine is running at highway speeds. The use of a high volume oil pump is an excellent choice when it comes to replacing a stock unit. You will have all the oil you need..even at idle.
