NGK Spark Plug Stock # 3481

The NGK Spark Plug Stock # 3481 is a standard resistor spark plug engineered for reliable ignition across a broad range of small engines and compact automotive applications. Built by NGK, a world-leading spark plug manufacturer with decades of proven performance, this plug delivers consistent cold-start reliability and combustion efficiency in both warm and cold operating conditions. Whether you're maintaining lawn equipment, generators, ATVs, or entry-level passenger vehicles, the DCPR6E is an OEM-quality replacement that meets exacting factory specifications.

This spark plug features a 12 mm thread diameter with a 0.749-inch reach and gasket seat design, allowing precise fitment into factory engine heads without modification or shimming. The resistor construction suppresses radio frequency interference (RFI) and electrical noise, protecting sensitive engine management systems and fuel injection controllers from electromagnetic interference. NGK's proven ceramic insulator material and nickel-alloy electrodes ensure long service life and stable electrode gap retention, reducing misfires and promoting clean, complete combustion across the engine's operating range.

Technicians and equipment owners trust NGK plugs for their durability and cost-effectiveness in routine maintenance and seasonal service intervals. Installation is straightforward—simply remove the old plug, gap-check if needed, and hand-thread the new unit into the cylinder head before final torque. This single-plug pack is ideal for users who prefer to replace one spark plug at a time or maintain a spare for emergency roadside repairs on small engines and compact vehicles.
