Product Details

The Boyesen Supercooler Water Pump Kit delivers enhanced cooling performance for powersports engines through advanced impeller design and precision engineering. This performance upgrade replaces the stock water pump impeller to increase coolant flow throughout the entire RPM range, helping maintain optimal operating temperatures during demanding riding conditions.

Key Features:

  • Cast aluminum construction for durability and corrosion resistance
  • Patented nautilus-style impeller design maximizes hydrodynamic efficiency
  • Increased coolant flow across all RPM ranges for improved thermal management
  • Direct replacement for OEM water pump impeller
  • Precision-engineered for optimal clearances and flow characteristics

The Supercooler Kit's nautilus impeller geometry creates more efficient water movement compared to stock impellers, reducing the risk of overheating during high-performance riding, racing, or slow-speed technical terrain. The cast aluminum construction ensures long-lasting performance in harsh operating environments while resisting cavitation and wear.

Had the product I was looking for at the lowest price possible.

Smooth

Easy shopping, however the confirmation from the warehouse and then the shipment to my home, took a week. For an overall product purchase it's fine, but if you have your car broken and you are waiting for the part, the waiting time is terrible.

Traslete Spanish please Grasias

Thank you foryou fast service, and knowledge. I will definitely be shopping again for my automotive supply needs.

I'm a new customer to Autoplicity and I just bought a Thule Bicycle Rack for a great price!! Autoplicity had a great price that didn't even compare to other websites prices. The shipping is super fast and it was in great packaging and shape when I received the bike rack. Thanks and I will definitely shop at Autoplicity again! Highly recommend!!

Everything was quick and easy. With discount for shipping, best price I could find on the internet. EDIT: Only problem I had was that the two day express shipping I had was a day late. I also never received a tracking number before I called CS. That was q

Smooth process and easy to follow instructions for checkout
