That's important because internal combustion engines require a precise combination of air and fuel to create the small explosions that give your car its power. The MAP sensor monitors the air ...

A fully functioning MAP sensor is necessary to maintain the right combination of acceleration, fuel economy, emissions and engine smoothness. When the throttle is wide open and air is rushing into ...

“Externally mounted sensors significantly increase aerodynamic drag, particularly by increasing the proportion of interference drag within the total aerodynamic drag,” study author Yiping Wang said.
