2008 Jeep Commander Knock Sensors

Carquest premium engine management products provide the right products for a wide range of domestic and import applications. Delivering the highest performance and durability under demanding conditions.

Building upon a foundation of premium full-line products established under NGK ignition and NTK oxygen sensor products, NTK’s expansion to technical sensors is part of our ongoing commitment to streamline product types and increase coverage under one premium brand: NTK, The Sensor Specialist. With over 80 years of automotive expertise, NGK’s family of automotive products are driven by extreme dedication to innovation, performance and quality. NTK is the only OE supplier with a full-line of technical sensors in the aftermarket for import and domestic vehicles. Drawing from OE experience, NTK sensors undergo extreme testing conditions that include thermal shock, vibration and OBD verification. NTK sensors are manufactured to ensure a quality that meets or exceeds OE specifications. As new vehicles incorporate connected and automated technologies, trust The Sensor Specialist for full-line market support and OE application technology.

Product Features:

• Reinforced and extra-strength components are used to reduce chance of part failure and prevent corrosion and moisture penetration. Mounting threads match OE for easy, worry free installation.
• NTK’s Ignition Knock Sensors are manufactured to operational performance standards to meet or exceed OE fit, form and function to ensure proper ignition timing. This advanced technology is used for durability, drivability and fuel economy.
• The Ignition Knock (Detonation) Sensor monitors vibrations caused by engine knock, or detonation, to alter the ignition timing and prevent detonation.

Manufactured to meet or exceed OE requirements; Delphi Knock Sensors help maximize engine performance with all fuels; Delphi Knock Sensors prevent against engine damage from pre-ignition knocking.

Product Features:

• 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
• 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

MotoRad Knock Sensors respond to a wide range of engine knock frequencies providing accurate engine condition to the ECM for optimal ignition timing. Highest quality piezoceramic element manufactured to tight tolerances for increased durability. All MotoRad Knock Sensors are designed to meet or exceed OEM specifications at our ISO TS16949 manufacturing facilities.

Product Features:

• Precision piezoceramic element ensures accurate response to a wide range of engine vibrations
• Manufactured using the highest quality OEM materials to ensure optimal performance and rugged durability
• Designed to meet or exceed all OEM specifications in fit, form & function
• Extensive product testing includes salt spray, high/low temperature impact, thermal cycling, vibration, drop among other tests, to ensure all sensors meet or exceed OEM specifications.

The Ignition Knock Sensor is a piezo Chrystal type sensor that reports harmonics within the engine block as the result of unfavorable ignition in the combustion chamber. The engine control module will make ignition timing and fuel injection pulse adjustments to correct the unfavorable ignition in the combustion chamber.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
• Where applicable, robust circuit board design increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
• Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
