Ngk V-Power Plugs 2438

The NGK V-Power Plugs 2438 is a premium resistor spark plug engineered for reliable ignition performance across a wide range of automotive applications. Designed for mechanics, restoration enthusiasts, and everyday drivers who demand OEM-equivalent quality, this spark plug delivers consistent cold-start capability and extended service intervals. The V-Power line represents NGK's commitment to superior electrode design and thermal management, making it an ideal replacement for factory spark plugs in both standard and performance-oriented engines.

This spark plug features an 18 mm thread diameter with a 0.460 inch reach and tapered seat configuration, ensuring proper seating and compression in compatible engine heads. The resistor design suppresses electromagnetic interference, protecting vehicle electronics and reducing noise on the ignition signal. NGK's V-Power electrodes are constructed to withstand higher combustion pressures and temperatures, resulting in cleaner combustion and reduced fouling—critical factors in maintaining fuel efficiency and minimizing emissions across varying driving conditions.

The NGK V-Power Plugs 2438 (MPN WR5) are best suited for applications requiring precise OEM fitment and reliable performance over extended intervals. Installation is straightforward for anyone with basic mechanical knowledge, requiring only a spark plug socket and gap tool to verify proper electrode spacing. Compatibility depends on engine specifications matching the 18 mm thread and 0.460 inch reach; verify your vehicle's requirements against the product specifications before purchase to ensure proper fit and safe operation.
