Detailed Product Description

The Standard Ignition AX63 Engine Intake Manifold Temperature Sensor features a direct mounting design that allows it to be installed firmly in the intake manifold without additional brackets or mounting hardware. It includes a single rectangular female connector with two male blade terminals, ensuring a secure and stable electrical connection. The sensor’s plug-in attachment method simplifies installation and replacement, making it a practical choice for maintenance and repair.

Finished in black, this sensor is engineered to meet the specifications required for emission control systems in various Nissan and INFINITI vehicles. It does not include mounting hardware or a wiring harness, so these components must be reused from the original sensor or sourced separately.
