Flow Kooler pumps also generate 22% more water pressure inside the engine block than other water pumps. This increased pressure helps suppress engine hot spots, steam pockets, and pinging. In addition to higher output, the Flow Kooler water pump is up to 32% more efficient than other pumps, meaning less horsepower is required to turn it.

The result is overall lower operating temperature by as much as 30 degrees when cruising at low speeds. All pumps are brand-new (not rebuilt) and are covered by a 2 Year Warranty.
