NGK G-Power Spark Plug 3207 Overview
NGK G-Power Spark Plug 3207 is built for drivers who need a reliable ignition service part with OE-focused construction.

Compatible With classic Ford Mustang, Thunderbird, and F-150 applications, as well as many Chevrolet, Buick, Pontiac, and Oldsmobile models, this NGK spark plug is a fitment-driven replacement for vehicles that call for a tapered-seat plug with a 14 mm thread and .460-inch reach.

Product Details
The NGK G-Power Spark Plug 3207 is part of NGK’s long-running OE supply program and reflects the brand’s focus on original-equipment standards, durability, and consistent performance. The platinum-tipped center electrode helps maintain dependable ignition characteristics, while the copper core supports heat transfer and steady operation.

Installation Notes and Fitment Tips
Verify the vehicle’s required spark plug gap before installation. This plug is listed with a .060-inch pre-gap, while many fitments note application-specific gap recommendations such as 0.054, 0.050, or 0.060 inches. Confirm the correct gap for the exact year, make, model, and emissions package before service.
