Bosch 0261231018 Knock Sensor for Porsche 964

The Bosch 0261231018 knock sensor is a precision engine management component designed to detect harmful engine detonation before it causes damage. This sensor is commonly found in Porsche 964 (911) Carrera 2 and Carrera 4 models from 1989-1994, where it cross-references to Porsche OEM part number 964.606.141.00.

How It Works:

The knock sensor mounts directly to the engine crankcase and uses a piezoelectric measuring element to detect high-frequency vibrations characteristic of engine knock. When the air-fuel mixture self-ignites prematurely (knocking), it creates damaging cylinder pressure spikes. The sensor identifies these vibrations and transmits a signal to the engine control unit (ECU), which adjusts ignition timing to prevent damage to the cylinder head gasket and cylinder head.

Key Features:

• Genuine Bosch OE-quality piezoelectric sensor technology
• Detects knock by measuring structure-borne noise and high-frequency engine vibrations
• Operates reliably at extreme engine temperatures
• Enables optimal ignition timing for maximum fuel efficiency and torque
• Direct replacement for Porsche part number 96460614100

Bosch knock sensors allow the engine management system to run more aggressive ignition timing while protecting against detonation, resulting in improved fuel economy and increased engine performance. The robust design ensures reliable signal output across varying fuel qualities and operating conditions.
