The Intake Air Temperature Sensor replaces the traditional MAF sensor and plugs directly into CSL carbon airboxes that use the OE BMW IAT sensor port, ensuring accurate data for your engine management system and reliable long-term performance.\u003c\/p\u003e\n\u003ch3\u003eWhy You Need It\u003c\/h3\u003e\n\u003cp\u003eUpgrading to a CSL-style carbon airbox changes the intake system layout and controls; the factory MAF sensor can no longer function as required. Without the correct intake air temperature (IAT) sensor, your engine risks inaccurate readings that can lead to poor performance or potential damage. Produced by OE manufacturer Hella, this OEM part provides a direct solution by maintaining OEM-quality installation and measurements in a CSL setup.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect CSL Fitment\u003c\/strong\u003e – Designed to work with carbon fiber CSL airboxes (E46 M3 S54 applications).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Quality\u003c\/strong\u003e – Ensures accurate intake air temperature readings for proper ECU function.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Upgrade\u003c\/strong\u003e – A cost-effective but essential part for anyone running a CSL-style intake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction\u003c\/strong\u003e – Built to withstand the heat and vibration of performance driving.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKeeps engine management accurate and reliable\u003c\/li\u003e\n\u003cli\u003ePrevents performance loss due to incorrect temperature signals\u003c\/li\u003e\n\u003cli\u003eEnsures a smooth install when fitting a CSL carbon intake\u003c\/li\u003e\n\u003cli\u003eAffordable and effective upgrade for CSL conversions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eApplication: BMW E46 M3 with CSL-style carbon fiber airbox (S54 engine)\u003c\/li\u003e\n\u003cli\u003eOEM Replacement: Compatible with CSL airbox setups where an IAT sensor is required\u003c\/li\u003e\n\u003cli\u003eIncludes: Intake air temperature sensor with pre-installed o-ring\u003c\/li\u003e\n\u003cli\u003eSupercedes BMW Part# 13621739510\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003ca href=\"https:\/\/svbimmer.com\/pages\/emissions-notice\" target=\"_blank\"\u003e\u003cstrong\u003eVIEW EMISSIONS NOTICE\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"BMW Genuine","offers":[{"title":"Default Title","offer_id":44881576067272,"sku":"13629899008","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0210\/4203\/6785\/files\/BMW-E46-M3-CSL-OEM-Hella-Intake-Air-Temp-Sensor.jpg?v=1766724302","url":"https:\/\/svbimmer.com\/products\/bmw-e46-m3-csl-oem-hella-intake-air-temp-sensor-13629899008","provider":"SVBimmer","version":"1.0","type":"link"}
