What is a MAP sensor and why would I need a 4 Bar version?

A MAP (Manifold Absolute Pressure) sensor measures the pressure inside your engine's intake manifold. The factory sensor typically reads up to 2 or 2.5 bar. A 4 Bar sensor is needed when you've modified your car to produce more than stock boost levels, allowing the engine computer to accurately read and manage higher pressures.

Does this kit come with everything needed for installation?

This kit includes the COBB 4 Bar MAP sensor and a wiring harness designed for a direct connection. You will need basic hand tools to remove the factory sensor and install the new one.

Can this sensor be used with any Subaru ECU tuning software?

This sensor is designed to be compatible with most aftermarket ECU tuning solutions for the Subaru platforms it fits. Your tuner will be able to utilize the data from this sensor to create a custom map for your vehicle's specific modifications.

Product Details

This kit includes a COBB 4 Bar MAP sensor and the necessary wiring harness to connect it to your Subaru WRX, Legacy GT, or Forester XT equipped with a plastic intake manifold. This sensor is designed to read higher boost pressures than the factory sensor, which is crucial if you've modified your vehicle's engine to produce more power. It's a well-built component that helps ensure your engine management system has accurate data to work with, preventing issues like over-boosting or incorrect fuel delivery.

The COBB 4 Bar MAP sensor is a popular choice for Subaru owners looking to tune their cars for increased performance. By accurately measuring boost up to 4 bar (approximately 44 psi of boost relative to atmospheric pressure), it gives your tuner the ability to safely dial in more aggressive engine maps. The included wiring harness is designed to be a direct plug-in solution, simplifying the installation process. This sensor is essential for anyone pushing their turbocharged Subaru beyond stock boost levels.

Please note that this part is not CARB approved and cannot be shipped to California. Always consult your tuner and follow proper installation procedures when upgrading critical engine components like a MAP sensor.
