Air temperature greatly effects an engines optimal ignition timing as well as the required fuel injection duration on an engine being controlled based on speed density calculations (i.e. no mass air flow meter). Most aftermarket engine management systems operate based on speed density principals and for these systems, accurate air temperature measurement is very important. In these cases the Inlet Air Temperature (IAT) sensor should be mounted just before the throttle to best measure the temperature of the air actually being ingested by the engine. This creates some challenges for forced-induction (turbocharged and supercharged) engines as this temperature rises and falls very quickly. In order to track the fast changing air temperatures, a fast-response Inlet Air Temperature sensor is required.
- Intake temperature sensor (IAT) M12X1.5.
- Very fast sensor due to the open element.
- Withstands temperatures up to 150 degrees. Supplied without connectors.
