Astemo Knock Sensors

Astemo offers ignition knock sensors for a wide range of vehicles, particularly many import models. These stock replacements are built to OEM specifications for performance and longevity. The knock sensor identifies the high-frequency engine vibrations characteristic of knocking and transmits a signal to the ECU. The aim is to obtain the maximum energy yield by starting ignition as early as possible. Engines with a knock sensor can reduce fuel consumption and increase torque. Astemo's quality control and attention to detail make their parts the go-to choice for many car manufacturers. Order the knock sensor model recommended for your application. Show Less
