Detailed Description

Standard Ignition AC508 is an OE-style idle air control valve used to regulate bypass air at idle on the specified Suzuki Grand Vitara and Suzuki XL-7 applications. By controlling idle airflow, the valve helps the engine maintain a steady idle speed when the throttle is closed and operating conditions change. This part cross-references Beck/Arnley 158-1015 for the same application.

What It Helps Address

• Unstable or fluctuating idle speed
• Stalling when coming to a stop
• Idle speed that is too high or too low
• Rough idle after warm-up
• Idle control faults related to the valve circuit

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. Inspect the throttle body, intake passages, and related sensors for carbon buildup or vacuum leaks, since those conditions can affect idle quality. Confirm fitment for 2001 Suzuki Grand Vitara and 2002-2006 Suzuki XL-7 before replacing the original valve.
