Omni Power USA 3, 4 & 5 Bar MAP Sensors
Omni Power USA MAP (Manifold Absolute Pressure) sensors use state-of-the-art bipolar op amp circuitry with thin film resistor networks built into each microchip. A specially designed silicon pressure sensor calculates pressure changes on a true linear 0–5 volt scale, automatically compensating for temperature changes to maintain 99%+ accuracy from 32°F to 180°F.
This true linear scaling means no re-tuning is required at different altitudes, unlike many competitors' sensors which can cause idle issues, drivability problems, or even engine damage when elevation changes.
The 4 Bar MAP sensor can precisely measure boost from 1–43+ psi while maintaining smooth OEM drivability, all in a housing that matches OEM dimensions for easy plug-and-play installation.
Key Features
- Cases designed to withstand over 130 PSI without leaking
- Operating range: -40°F to 260°F (-40°C to 127°C)
- Ultra-fast response time: 10% to 90% of the pressure scale in 0.001 seconds
- Automatic temperature compensation
- True linear scaling for perfect drivability at all boost and vacuum levels
- Compatible with all aftermarket engine management systems
- Minimum 99% accuracy across full range under all conditions
- Improves engine operation, allows higher boost, and enhances drivability
- Direct plug-and-play with OEM dimensions and appearance
- Hand-assembled, pressure and function checked in the USA for quality control

What clients say
-
Really fast and high quality customer support, my order got to me faster than the quoted time too. No complaints
-
The team took a mostly broken car after some work done elsewhere, and have systematically made it reliable and fast for a fair price. The staff are invested in the work they do which also makes a big difference.
