Description
Sustained cooling performance is critical during extended racing sessions—thermal cycling and pressure spikes can compromise water flow and allow temperatures to creep into the danger zone. The BOYESEN Impeller Pump WPI-32A counters this with optimized impeller geometry that reduces cavitation and hydraulic friction, keeping coolant circulating efficiently while you extract maximum power from your YZ or WR. Measurable gains in thermal stability translate directly to extended engine life and consistent horsepower delivery lap after lap.
