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

The Blox Racing MAP (Manifold Absolute Pressure) bypass valve replaces the factory aquarium-style check valve with a precision-engineered billet aluminum component designed for turbocharged and supercharged applications.

Key Features:

• CNC-machined from high-quality billet aluminum construction
• Eliminates check engine lights commonly triggered in forced induction setups
• Protects factory MAP sensor from damage during high boost conditions
• Direct replacement for OEM check valve with superior durability
• Clean, professional appearance under the hood

This bypass valve is essential for maintaining proper MAP sensor operation while running elevated boost levels. By regulating pressure to the MAP sensor, it prevents false readings that trigger diagnostic trouble codes while protecting the sensor from boost pressure that exceeds factory specifications.
