Bosch Knock Sensor (OE 13676440/9358037/94460614500/7568801)

This is a Bosch knock sensor, an OE replacement part designed to help protect your engine. It works by listening for the tell-tale pinging sound of pre-ignition, or 'knock,' which can damage your engine if left unchecked. When it detects knock, it signals the engine control unit (ECU) to adjust ignition timing, preventing damage and helping to maintain optimal fuel economy. This sensor is built to OE specifications, ensuring it functions just like the original part it replaces.

Bosch knock sensors are well-built to handle the demands of detecting engine knock across a range of fuel types. By allowing the ECU to make precise adjustments to ignition timing, this sensor helps your engine run more efficiently, potentially improving fuel consumption by up to 9%. This part fits a variety of vehicles, including many Porsche 944 and 968 models, various Saab 900 and 9000 series cars, and numerous Volvo models like the 240, 740, and 940 series.
