The Bosch 0986JG0830 is an Original Equipment (OE) quality engine knock sensor designed to detect engine detonation and provide critical feedback to the engine control module. This sensor monitors vibrations and abnormal combustion events, allowing the ECU to adjust ignition timing to prevent engine damage and maintain optimal performance.

Key Features:

• OE quality construction meeting or exceeding original equipment specifications
• Precision piezoelectric sensor element for accurate knock detection
• Durable housing resistant to engine heat, vibration, and contaminants
• Direct replacement for factory knock sensor on select 1991-2004 Nissan and Infiniti vehicles
