The Hondata 4 Bar Map Sensor is a critical performance upgrade for your S2000, R18, or L15B Turbo Civic. This plug-and-play sensor replaces the factory map sensor and allows for accurate measurement of boost levels up to 58 PSI (4 bar). With the Hondata 4 Bar Map Sensor, engine management systems such as the Hondata K-Pro or FlashPro can adjust fuel and ignition maps with precision, resulting in improved performance and power gains.
please note that the L15B Turbo requires two MAP sensors.
