NGK Spark Plug Stock # 1049

The NGK Spark Plug Stock # 1049 (MPN: B8EFS) is a non-resistor spark plug engineered for reliable ignition in small engines and light-duty applications. This standard NGK spark plug features a 14mm threaded design with a 0.708-inch reach and tapered seat, making it a direct fit for engines originally equipped with NGK OEM specifications. The non-resistor construction delivers consistent spark performance without frequency suppression, ideal for applications where radio interference is not a primary concern.

NGK's manufacturing standards ensure precise electrode gap, ceramic insulation integrity, and corrosion resistance across extended service intervals. The tapered seat design provides a secure seal within the cylinder head, minimizing combustion gas leakage and maintaining stable compression. The 14mm thread diameter and 0.708-inch reach are critical dimensions—selecting the correct reach prevents electrode contact with piston crowns while ensuring optimal spark position within the combustion chamber. NGK spark plugs are recognized for cold-start reliability and consistent firing across varying load conditions, backed by rigorous quality control and decades of OEM partnerships.

This spark plug is suited for small gasoline engines used in lawn equipment, portable generators, pressure washers, and light industrial machinery. Users performing routine maintenance or troubleshooting ignition issues will find this plug a cost-effective, direct replacement for OEM specification requirements. The non-resistor design is standard in many older equipment models and applications where engine simplicity and minimal electronics are preferred. Single-unit sales allow operators to replace plugs individually as needed without committing to multi-packs.

NGK maintains a substantial market share in small-engine OEM supply, reflecting the brand's focus on manufacturing consistency and thermal performance. The B8EFS designation identifies this plug within NGK's standard range, making cross-reference with equipment documentation straightforward. Availability of single units through TacticalSurplusUSA ensures quick replacement without excess inventory when spark plug maintenance is required.
