The IAG Performance Map Sensor Adapter enables you to go beyond the limits of 23 psi with your Subaru. The OEM map sensor is limited to 23 psi and if you want to exceed that pressure, you are required to install an aftermarket MAP sensor*. Our adapter Features 1/8" NPT female threads, which permits the use of various MAP sensors. We frequently use the AEM 3.5 bar sensor (sold separately).

Our map sensor adapter is engineered and manufactured in our facility in Westminster, Maryland. Each product is machined from a single piece of 6061 billet aluminum and then anodized black for a protective finish. Each adapter features our engraved piston logo.

Note: Any aftermarket sensor will require tuning.
