• Delphi knock sensors help maximize engine performance with all fuels; Delphi knock sensors prevent against engine damage from pre-ignition knocking
• Calibrated for a wide variety of frequencies to detect shifts, and adjust to provide accurate signals to help maximize engine performance
• Flat frequency response allows the same sensor to be used on different engines and the sensor responds to knock frequencies higher than the primary frequency
• Ground-isolated design with 2-wire shielded harness helps protect the sensor signal from electro-magnetic interference (EMI); Self-generating piezoelectric design requires no power to the sensor
