Blox Racing BXFU-00302-SI MAP Bypass Valve Billet Aluminum Engine Crankshaft Position Sensor Bracket

The Blox Racing MAP bypass valve offers a clean, performance-oriented solution to replace the factory aquarium-style check valve found on many turbocharged and supercharged engines. Precision-machined from high-quality billet aluminum, this valve provides both functional benefits and improved underhood aesthetics.

Key Features:

• CNC-machined billet aluminum construction for durability and heat resistance
• Eliminates check engine light issues commonly associated with forced induction setups
• Protects factory MAP (Manifold Absolute Pressure) sensor from damage during high boost applications
• Direct replacement for OEM check valve with improved flow characteristics
• Silver anodized finish for corrosion resistance and clean appearance

This bypass valve is essential for forced induction applications where boost pressure exceeds factory specifications. By regulating pressure to the MAP sensor, it prevents sensor overload while maintaining accurate readings for proper engine management and fuel mapping.
