The Bosch 0280130085 is a fast-response IAT sensor using an open (exposed) NTC thermistor element. Unlike the M12 thread NTC sensors where the element is sealed inside a metal housing, the open element here is directly exposed to the air stream — significantly reducing the thermal time constant and allowing the sensor to track rapid changes in intake air temperature accurately.
This makes it the correct choice for applications where intake air temperature changes quickly: turbocharged engines with intercoolers, airbox measurements on NA race engines, or post-throttle temperature measurement where charge temperature varies with throttle position and load.
The 2-pin Jetronic connector and M6 flange mount make it compatible with a wide range of intake manifolds and plenums. The O-ring provides sealing at the flange mount face.
