SVTDF 4 Bar Map Sensor for Fiesta ST and Focus ST

Designed to directly replace the factory 2.5 Bar sensor, this upgrade allows accurate boost readings up to 44 psi (vs. the stock ~21 psi limit), making it essential for high-boost, tuned, or big-turbo builds.

Compatible with both the Fiesta ST and Focus ST (they share the same MAP sensor electronics), this sensor is a drop-in performance upgrade—with one minor modification.

Note: Due to a slight difference in the tab design, you'll need to grind or trim the locating tab on the OEM harness connector to ensure proper fitment. This is a simple 2-minute job (see picture) and does not affect functionality or the integrity of the connector.

Features:

   Accurately reads boost up to 4 Bar (44 psi)

   Fit for Fiesta ST & Focus ST

   Supports custom tuning and high-performance applications

   OE-style connector with plug-and-play functionality (after tab modification)

   Built to withstand high boost and harsh under-hood conditions

Requires a tune revision to scale the sensor correctly - If you are a tuner, please reach out for scaling information.
