The Hondata 4 Bar Map Sensor is a premium aftermarket upgrade tailored for B-Series Honda and Acura vehicles. It replaces the factory map sensor, unlocking the ability to accurately measure boost levels up to 58 PSI or 400 kPa (4 bar), a substantial improvement over the factory 10-11 psi (0.7-0.8 bar) limit. This enhancement is invaluable for high-performance builds, ensuring optimal power delivery.

This plug-and-play upgrade requires no modifications to the engine harness or ECU. Once installed, it empowers engine management systems like the Hondata K-Pro or FlashPro to precisely measure boost levels, enabling fine-tuned fuel and ignition adjustments. For discerning tuners seeking peak performance, the Hondata 4 Bar Map Sensor is the ultimate choice.
