NGK Spark Plug Stock # 1716-Box of 100

The NGK Spark Plug Stock # 1716-Box of 100 is a premium resistor spark plug engineered for reliable ignition across a wide range of standard automotive applications. Built by NGK, a global leader in spark plug manufacturing, this bulk pack of 100 units delivers consistent cold-start performance and efficient combustion. The 14mm thread design with 0.749-inch reach and gasket seat configuration makes these spark plugs compatible with most conventional engine architectures, from light-duty vehicles to small-displacement marine and small equipment engines.

These spark plugs feature resistor technology that suppresses radio frequency interference (RFI), protecting vehicle electronics and onboard communication systems from ignition noise. The gasket seat design creates a reliable, metal-to-metal seal without requiring additional crush washers, ensuring leak-free installation and repeatability across multiple engines. NGK's proprietary electrode geometry and ceramic insulation optimize heat dissipation and thermal range compatibility, extending spark plug life and reducing misfire probability in high-mileage or demanding conditions. The standardized CS6 specification ensures drop-in compatibility with original equipment specifications across numerous platforms.

Fleet operators, small engine mechanics, and equipment maintenance professionals benefit most from this 100-count bulk package, which reduces per-unit costs and ensures consistent inventory for scheduled service work. Installation requires only a spark plug socket and wrench; no special tools are needed. The gasket seat eliminates the need for crush washers, streamlining replacement procedures and minimizing installation error. These plugs are suitable for lawn mowers, generators, small aircraft, motorcycles, ATVs, and legacy automotive platforms that specify 14mm, 0.749-inch reach plugs, making this box an essential maintenance stock for any professional service facility or serious hobbyist.
