Holstein 2KNC0290 Ignition Knock Detonation Sensor OE Replacement

The Holstein Parts 2KNC0290 is a direct OE replacement ignition knock (detonation) sensor engineered to restore precise engine management function. The knock sensor monitors the engine block for abnormal vibration frequencies caused by detonation or pre-ignition, transmitting that data to the vehicle's ECU so it can retard ignition timing and protect internal engine components from damage.

Key Features:

• Direct OE Replacement: Precision-engineered to exactly duplicate the fit, form, and function of the original factory sensor
• ECU Communication: Sends accurate voltage signals to the ECU to allow real-time ignition timing adjustment and prevent engine knock damage
• Premium Materials: Built with high-quality materials for long-term durability and resistance to high engine operating temperatures
• OE-Matched Connectors: Features exact OE connector design and attachment points for a straightforward, trouble-free installation
• Voltage Tested: Fully tested to confirm output voltage matches OE specifications before leaving the factory
• Anti-Static Packaging: Arrives in a protective anti-static bag to safeguard sensitive electronic components during shipping and handling
• Warranty: Backed by Holstein Parts' 3-year / 36,000-mile warranty

Holstein Parts sources components from the same factories that supply original equipment manufacturers, ensuring each knock sensor meets or exceeds OE standards. This sensor is an ideal solution for restoring proper detonation detection and engine timing control.
