Description
Take cooling to the next level on your Kawasaki Ultra 250/260/300/310 with the R&D 5-Port Cooling Manifold. This billet replacement for the stock pump-mounted block adds multiple extra ports, enabling additional cooling lines to the engine and optimized flow through the oil cooler – slashing temps and eliminating heat-related power loss.
Advanced Cooling Features
- Five-port design for flexible cooling circuit expansion
- Direct engine cooling reduces head and block temperatures
- Enhanced oil cooler routing lowers oil temps under boost
- Decreases water to waterbox for reduced backpressure
High-output Ultras (especially modded 300/310s) generate massive heat. Stock cooling falls short, causing fade and detonation risk. The 5-port manifold fixes this comprehensively, delivering cooler operation, sharper response, and sustained top-end performance.
Precision Billet Build
CNC-machined from billet with marine-grade finishes, this manifold is built to handle pressure, heat, and corrosion for long-term reliability.
- Can drop temps 25-50 F in high-load scenarios
- Supports big-power builds without overheating
- Improves throttle crispness by reducing heat fade
- Proven on race-prepped Ultra platforms
Run harder, longer, and cooler.
Installation Guidance
Replace OEM block at pump, route additional lines, bleed thoroughly. Monitor temps post-install. May pair with thermostat upgrades for full control.
Maximize cooling on your Kawasaki Ultra with the R&D 5-Port Manifold.
