NGK Spark Plug Stock # 2953

The NGK Spark Plug Stock #2953 (YR5GP) is a G-Power Platinum resistor spark plug engineered for reliable ignition performance across a wide range of small engines and automotive applications. This 14mm threaded spark plug features a 0.460-inch reach and tapered seat design, making it a direct fit for engines originally specified with NGK YR5GP plugs. NGK's G-Power Platinum line combines a precious metal center electrode with a platinum-enhanced ground electrode to deliver consistent spark initiation and extended service life compared to conventional copper-core designs.

The tapered seat configuration ensures proper sealing without requiring a crush washer, simplifying installation and reducing the risk of over-torque damage to the cylinder head. The resistor element suppresses electromagnetic noise, protecting vehicle electronics and radio systems from ignition-induced interference—a critical feature in modern engine management systems. The 0.460-inch reach is precisely calibrated to position the firing end at the optimal depth within the combustion chamber, ensuring complete fuel mixture ignition and efficient power delivery. NGK Spark Plug YR5GP replacements are manufactured to strict quality tolerances and are compatible with OEM specifications for proper engine operation.

This spark plug is ideal for owners maintaining small-displacement engines, lawn equipment, generators, and compact recreational vehicles where original NGK YR5GP specifications apply. Technicians and DIY enthusiasts appreciate NGK's consistency—every plug is pre-gapped and ready to install. Whether performing routine maintenance on aging equipment or rebuilding an engine, having the correct OEM-equivalent spark plug ensures predictable starting, smooth idling, and fuel efficiency.
