A map sensor adapter is needed to adapt the aem sensor to the oem style spot.
5 bar map sensor sti.
Omni power usa 5 map manifold absolute pressure sensor uses state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip.
This is a boost sensor that measures how much boost you are running so that your ecu can compensate with fuel.
Here are the details.
A must have when your vehicle begins having moderate bolt ons for both piggy back or standalone engine management systems.
An aem 3 5 bar or aem 5 bar sensor is recommended on most applications unless boost will be lower than the limits by a good margin.
Most subarus are equipped with either a 2 5 or 3 bar map sensor from the factory which allows accurate reading up to either 21 5psi or 28 8psi respectively.
Pressure changes are calculated on a true linear 0 5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes.
Psia is referenced to absolute zero.

Iag map sensor adapter for 2002 07 subaru wrx 04 18 sti 04 08 fxt enables you to go beyond the limits of 23 psi with your subaru.
The 3 5 bar sensor can read up to about 36 psi so if boost will be near or higher than that the 5 bar is recommended.
Aem offers high quality stainless steel psia sensors in 15 1bar 30 2bar 50 3 5bar 75 5bar and 100 7bar.
On this page you are looking at the omni power 5 bar map sensor.
Subaru sti 2004 5 bar map sensor map sti15 5br omni power usa 3 4 5 bar map manifold absolute pressure sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip.
For vehicles targeting boost values higher than that an upgraded sensor is required for accurate measurement and control.
Our adapter features 1 8 npt female threads which permits the use of various map sensors.
