Specifications
Part Details:
Tuning required. Installing this adapter requires custom tuning or an appropriate COBB Stage Power Package map matching your mechanical configuration. Consult with COBB or an authorized ProTuner before installing.
Most Subarus come from the factory with either a 2.5 or 3 bar MAP sensor, accurate up to 21.5psi or 28.8psi respectively. Push boost past that ceiling and the factory sensor simply runs out of range, delivering inaccurate readings right when precise boost control matters most. This COBB billet aluminum adapter lets you mount an upgraded aftermarket pressure sensor using 1/8″ NPT threads, giving high-boost builds the accurate, OEM-like sensor fitment they need.
Finished in black anodizing with a laser etched “C” logo, and includes an o-ring and hardware for a leak-free installation directly into the throttle body.

Frequently Asked Questions
Do I need this if I’m not pushing high boost?
Most factory MAP sensors read accurately up to 21.5-28.8psi depending on the vehicle. If your build stays under that range, an upgraded sensor and adapter likely isn’t necessary yet.
Do I need a tune to install this?
Yes. This adapter requires custom tuning or a compatible COBB Stage Power Package map matching your mechanical setup. Do not install without confirming tuning support first.
What sensor does this work with?
Any aftermarket pressure sensor using 1/8″ NPT threads, letting you choose the sensor range that matches your build’s target boost.
