NGK Spark Plug Stock # 6953

The NGK Spark Plug Stock # 6953 is a premium OEM-grade ignition component engineered for reliable engine starting and consistent combustion across a broad range of automotive applications. NGK spark plugs are trusted by mechanics, fleet operators, and vehicle enthusiasts for their durability and performance in demanding conditions. This resistor-type spark plug is designed to reduce radio frequency interference while maintaining optimal firing efficiency, making it an ideal replacement choice for scheduled maintenance or performance restoration.

Built with NGK's V-Power electrode technology, this spark plug features a 14 mm thread diameter and a 0.749 inch reach, designed to seat securely in the cylinder head with a gasket seal for a leak-free fit. The resistor construction suppresses electromagnetic noise generated during combustion, protecting sensitive vehicle electronics and radio systems from signal degradation. The compact form factor—measuring 1 by 0.85 by 3.5 inches and weighing just 0.1 pounds—ensures straightforward installation in tight engine compartments without modification to existing hardware.

This spark plug performs exceptionally well in four-cylinder and inline-six engines where consistent ignition timing is critical for fuel economy and power delivery. Installation is straightforward for both DIY mechanics and professional technicians—simply remove the old plug, verify the gap (pre-set by NGK), thread the new unit into the spark plug well, and torque to manufacturer specifications. Cross-reference the NGK BKR5E-11 designation with your vehicle's service manual to confirm fitment before purchase, as thread size and reach specifications are critical for proper engine operation and longevity.
