While this is more accurate than using the factory MAF sensor that sits before the turbo, the OBD1 IAT sensor does have one major flaw; \u003cstrong\u003ethe response time\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe principle of IAT sensors are all the same, in the core of the sensor lies a NTC thermistor that changes resistance proportional to the temperature. The ECU can then use the resistance value to determine the air's temperature. The problem with the OBD1 is that the NTC thermistor is shielded around plastic. Plastic is an insulator and does not conduct heat very well. This results in delayed feedback to the ECU.\u003c\/p\u003e\n\u003cp\u003eHRD's fast response IAT sensor is hand made, using specially manufactured thermistors that are matched very closely to the OEM Sensor's resistance curve. This ensures that the ECU reads the correct temperature at an almost instantaneous speed.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eOBD1, and NPT sensors are matched to the Honda sensor PN: \u003cspan data-olk-copy-source=\"MailCompose\"\u003e37880-P05-A00\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why can't I use the GM IAT sensor? Doesn't that sensor read fast?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The OEM Honda ECU does not have the ability to change scaling on the IAT sensors. The GM sensors use a different resistance curve than Honda sensors, so it would read incorrect temperatures. However if you have a standalone ECU, such as a Motec or Haltech, you would be able to program the resistance curve to use virtually any temperature sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis sensor has been scientifically tested against the OBD1 IAT sensor, and reads temperatures up to \u003c\/span\u003e\u003cspan\u003e1200\u003c\/span\u003e\u003cspan\u003e% faster than the OBD1 plastic sensor.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCustom manufactured high precision (1%) thermistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003eOpen thermistor design for near-instant response time\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLifetime warranty against defects\u003c\/li\u003e\n\u003cli\u003eTitanium hardware included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote: We've done testing on various Honda sensors, and concluded that this sensor will NOT work for the S2000. \u003c\/strong\u003e\u003c\/p\u003e","brand":"HRD","offers":[{"title":"Default Title","offer_id":51939837968677,"sku":"HRD-IAT-OBD1","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/7706\/4741\/files\/HRD-IAT-OBD11.jpg?v=1777717712","url":"https:\/\/saikospeed.com\/products\/hrd-honda-fast-response-iat-sensor-obd1","provider":"Saikospeed","version":"1.0","type":"link"}
