NGK Spark Plug - 4288

While NGK plugs often come with a gap setting, you should always check the gap against your vehicle's specific manual requirements before installation.

This is a standard platinum plug. If your engine is modified for high boost or racing, you may require a different heat range or an Iridium-series plug.

Typically, platinum plugs last longer than nickel ones, but you should follow your vehicle manufacturer's recommended service interval, usually between 30,000 to 60,000 miles.

The 16mm size is common, but it is smaller than the traditional 21mm (13/16 inch) plugs found in older vehicles; ensure you have the correct socket size.

It reduces electrical interference caused by the spark, protecting your car's radio and ECU from signal noise.

Verify that the plug is fully seated and the ignition wire is securely clicked onto the SAE connector.

Ensure the spark plug gap is set exactly to the vehicle manufacturer's specification.

Apply a penetrating oil around the base of the plug and allow it to sit before attempting to loosen again to avoid snapping the thread.
