SpeedFactory MAP Sensor 4 BAR - K Series

SpeedFactory 4 Bar MAP Sensor

If you’re running boost—or planning to—your ECU can only be as smart as the data it’s getting. The SpeedFactory 4 Bar MAP Sensor is built for people who actually drive their cars hard and want consistent, trustworthy readings whether you’re cruising, ripping through gears, or leaning on boost at the track. This sensor gives your engine management system a clean, true linear 0–5V signal across the entire pressure range, so tuning stays predictable and drivability stays smooth.

What sets this MAP sensor apart is how stable it is in the real world. Temperature swings, altitude changes, and weather don’t throw it off. The sensor automatically compensates for temperature, staying at least 99% accurate from freezing cold mornings to full heat-soak conditions. That means no chasing your tune when you travel, no weird fueling changes, and no guessing if the sensor is lying to you.

Response time is another big deal here. This sensor reacts almost instantly to pressure changes, so when boost comes in fast, your ECU sees it immediately. The result is smoother throttle response, cleaner boost control, and better overall drivability—especially on turbo setups that hit hard. It’s also a direct plug-and-play replacement for the factory MAP sensor, so installation is simple and the engine bay keeps an OEM look.

Every SpeedFactory 4 Bar MAP sensor is hand-assembled, pressure-tested, and function-checked in the USA before it ships. This is the kind of part you install once and trust, whether you’re street driving, tracking the car, or pushing the limits of your setup.
