Unlock the full potential of your Polaris Patriot 850 Boost with the Silber Turbos High Flow Airbox Valve. Designed as a direct upgrade to the factory reed valve, this plunger-style valve uses a positive rubber seal for a 100% airtight seal under boost while opening effortlessly under minimal vacuum. The result? Instant throttle response, stronger low-end power, and drastically reduced turbo lag.
Unlike restrictive factory parts, the low-profile oval design of this valve maximizes airflow without disrupting airbox volume, ensuring smooth, consistent performance. Precision CNC-machined from 5-axis billet aluminum and paired with a Nylatron rubber-sealed valve, it offers unmatched durability and reliability in demanding riding conditions.
Whether your sled is stock or tuned, this high-flow airbox valve adapts seamlessly and keeps performance consistent season after season. Easy to install with the included hardware, it’s one of the simplest and most effective upgrades you can make for your Patriot Boost. Silber Turbos delivers the performance edge riders trust.
Polaris Patriot 850 Boost Airbox Valve High Flow – Silber Turbos Performance Engineering
The Silber Turbos Airbox Valve is the result of years of development, testing, and refinement. Designed specifically for the Polaris Patriot Boost 850, this valve provides the one thing your turbocharged sled needs most—uncompromised airflow and immediate throttle response.
The stock reed valve works when new but degrades quickly as reed pedals wear out. This leads to inconsistent airflow, slower response, and lost performance.
Our plunger-style valve uses a positive rubber seal that guarantees a 100% boost-tight seal while opening instantly with minimal vacuum. This results in faster throttle response, stronger low-end torque, and dramatically reduced turbo lag.
The low-profile oval design maximizes airflow surface area while maintaining optimal airbox volume. This eliminates restrictions and prevents turbulence for clean, efficient airflow at any boost level.
Constructed from CNC-machined 5-axis billet aluminum with a Nylatron rubber-sealed valve, this system combines strength and long-term reliability with lightweight performance.
