Where are the knock sensors located on a 1998 q45?

On a 1998 Infiniti Q45, the knock sensors are located on the engine block, specifically beneath the intake manifold. There are typically two knock sensors, one for each bank of cylinders, and they are mounted on the lower part of the engine to detect vibrations that indicate knocking or pre-ignition. Accessing them often requires removing the intake manifold due to their placement.
