NGK Spark Plug Stock # 3284

The NGK FR5GP spark plug (Stock #3284) is a premium G-Power Platinum spark plug engineered for reliable ignition across a wide range of small gasoline engines. This 14mm threaded spark plug features a 0.749-inch reach and gasket seat design, making it a direct replacement for numerous automotive and power equipment applications where OEM ignition performance is non-negotiable.

NGK's G-Power Platinum technology delivers superior spark energy and extended service intervals compared to conventional copper-core plugs. The resistor-type construction suppresses radio frequency interference, which is critical in modern engine management systems that rely on precise sensor feedback. The platinum center electrode and platinum-enhanced ground electrode resist erosion and oxidation, maintaining consistent gap voltage over thousands of firing cycles. This translates to cleaner combustion, improved fuel economy, and fewer misfires—especially important in engines operating under varying load conditions or extreme temperatures.

This NGK spark plug suits lawn equipment, small generators, marine engines, motorcycles, and compact automotive applications where the 14mm thread and 0.749-inch reach specification match OEM requirements. Technicians and equipment owners choose NGK FR5GP replacements when original equipment performance and longevity are the priority. The gasket seat design ensures a secure, leak-free fit in the cylinder head, critical for maintaining compression and preventing electrode fouling from combustion gases.

NGK is recognized globally as an OEM supplier to major engine manufacturers and holds strict quality standards for spark plug manufacturing. The FR5GP is sold as an individual unit, allowing precise replacement of worn or damaged plugs without excess inventory. For applications using multiple spark plugs, order the quantity needed for your engine configuration.
