NISSAN 16175-AR200 Throttle Body Gasket

The genuine NISSAN part number 16175-AR200 throttle body gasket (K GSKT-THROT CH) is engineered to provide a hermetic, airtight seal between the throttle body and the intake manifold. At this critical junction in the intake system, proper sealing is vital for precise air intake metering. If the gasket degrades or fails, unmetered (false) air enters the cylinders, upsetting the air-fuel ratio regulated by the engine control unit (ECU).

Operational Importance and Symptoms of Wear:

Hardening, cracking, or deformation of the throttle body gasket leads to a loss of intake vacuum. Common symptoms include an erratic or elevated idle speed, hard cold starting, hesitation under acceleration, and illumination of the Check Engine light (typically accompanied by a DTC indicating a lean mixture). Whenever the throttle body is removed, serviced, or cleaned, replacing the gasket is a mandatory service procedure.
