Product Description
The Walker Products 242-1357 Ignition Knock Sensor is an OE Replacement component that monitors engine vibrations to detect knocking or detonation events. These knock sensors are a critical part of the engine control system, allowing the ECU to adjust ignition timing in real time to prevent spark knock—a condition that can cause internal engine damage, reduced fuel economy, and drivability issues. Each engine knock sensor is engineered to match OE specifications for frequency range, sensitivity, and electrical output. Our automotive replacement detonation sensors are tuned to detect the specific resonant frequency of knock in each engine platform, enabling precise spark retard when knock is detected. Built from high-quality, heat- and oil-resistant materials, these sensors are designed to endure the harsh conditions of the engine block and cylinder head. With exact OE fitment, they install directly into the original threaded locations and connect using factory-style electrical terminals. Our sensors restore proper knock detection, improve engine safety, and support optimal ignition performance across a wide range of gasoline applications. Compatible with Ford F-250 Super Duty/F-350 Super Duty/F-450 Super Duty/F-550 Super Duty 2005-2010 and F-53 Motorhome Chassis 2009. See Amazon Confirmed Fit to check your vehicle's compatibility.
