BIKEMAN PERFORMANCE Billet Head Kit High Altitude for 2024 Polaris Patriot 9R RMK Khaos Slash 155 04-318-H-900

If you're running your Polaris at elevation, standard engine tuning leaves power on the table and heat management compromised. The BIKEMAN PERFORMANCE Billet Head Kit recalibrates your combustion chamber for the thinner air above 6,000 feet, delivering measurable horsepower gains while keeping cylinder temperatures in check. At altitude, this translates to the throttle response and reliability you expect from a premium snow machine.

This is a bolt-on upgrade that requires professional tuning to unlock its full potential. You'll need to dial in the R9 ECU and run minimum 91-octane fuel to realize the 8–9 hp mid-range and 7–8 hp peak gains. Pair it with the recommended NGK BPR9ES spark plug for optimized ignition performance across your entire powerband.
