Rock solid construction and improved cooling make the Stewart High Performance Water Pump the only choice for our personal and project cars here at BimmerBum.Up to
- 20% increase of water flow over stock pump
- Twice as efficient as factory pump
- Much less parasitic drag than other pumps
- Racing or Stock Factory Replacement applications
- Stainless steel impeller
- Heavy duty bearing
- High quality water seal
Take a look at the pictures of the Stewart pump next to a metal impeller Graf pump. The quality in the Stewart pump is obvious and extends beyond things you can see like the water jacket and CNC impeller to things you can't see like the larger, better bearing and the carbon seal.
