OMNI Power 4 Bar MAP Sensor for Subaru WRX 2008-2014 & Legacy GT 2005-2009

OMNI Power


Omni Power USA 3 & 4 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.

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. The unique ability to compensate for temperature changes allows the Omni Power USA 4 Bar MAP sensor to remain a minimum of 99% accurate from 32 degrees F to 180 degrees F through out its range of scale.

With the true linear pressure vs. voltage scale there is never a need to re-tune at different altitudes as with other sensors. Competitors sensors on the market don't have true linear scaling which can cause your engine to go out of tune with elevation changes, often resulting in idle problems, poor drivability, and catastrophic engine damage.

Omni Power 4 bar MAP sensors can precisely calculate boost pressure from 1-43+ psi while still allowing smooth stock OEM drivability at any boost level. Conveniently packaged in an OEM dimensional housing for easy install and an OEM look. 

Key features:

This is a boost sensor that measures how much boost you are running so that your ECU can compensate with fuel. A true must have when you start to add a few bolt-ons for both piggy-back or standalone engine management systems.

  • Here are the details:

    • Good for temperatures as low as -40°F to 260°F
    • Going from 10% of the pressure scale to 90% takes .001 seconds
    • Direct replacement for your stock MAP sensor
    • Plugs into the stock harness


  • 2008-2014 Subaru WRX
  • 2005-2009 Subaru Legacy GT
