1986-1993 Honda Civic B16/B17/B18 Blox Racing MAP Bypass Valve, Type-B, Firewall Mounted, Black

The BLOX Racing MAP Bypass Valve is designed for use with forced-induction applications.

The MAP Bypass Valve completely blocks boost from reaching the MAP sensor, thus simulating a wide-open-throttle reading at the vehicle's ECU. The vehicle is then prevented from running in "limp" mode so that no check-engine light appears. The end result is protecting the MAP sensor from being damaged.

MAP Bypass Valves are available as internal or external units. Universal Application: Hose-end MAP sensors
