Weber Marelli type 3 Bar MAP Sensor.
Will Fit: Ford: Sierra / Escort Cosworth, Fiat Coupe, Lancia, Ferrari
Will also fit many other cars and aftermarket engine management systems.
THE ONLY AFTERMARKET 3 BAR THAT WORKS.
We use an on chip barometric sensor that is calibrated to exact same specifications as the original Marelli was. Every Sensor checked for calibration as you can see in the last picture.
