Mitsubishi Suzuki SX4 Intake Air Pressure Sensor 717421 18590-72F21 E1T26571A Precise Measurement

Mitsubishi, Suzuki, and Tianyu owners note that the intake pressure sensor (OEM 26571; corresponding original numbers 18590-72F21, E1T26571A) uses a high-density ceramic sensing element and sealed housing to resist oil contamination and temperature fluctuations in the engine bay. It precisely monitors intake manifold pressure and transmits signals to the ECU in real time to ensure proper air-fuel ratio and idle stability, avoiding acceleration hesitations or abnormal fuel consumption. Installation is simple, no special tools required; just plug in replacement to restore factory performance.
