Spark Plug Stock 4764

The NGK Spark Plug Stock 4764 (BUR7EQP) is a precision-engineered ignition component designed for drivers and mechanics who demand reliable engine performance and consistent combustion efficiency. As an OEM-quality spark plug, it serves as the critical bridge between your vehicle's electrical and fuel systems, ensuring every firing cycle delivers optimal flame kernel initiation. Whether you're maintaining a stock engine or fine-tuning a modified build, this NGK plug provides the dependable spark energy needed for smooth idle, responsive throttle, and fuel economy across a wide operating temperature range.

NGK's BUR7EQP electrode design uses a nickel-alloy center wire and carefully contoured ground electrode geometry to minimize voltage demand while maximizing spark duration—critical for efficient combustion in both naturally aspirated and moderately boosted applications. The compact 0.9-inch diameter and 3.8-inch length fit standard cylinder head configurations, and the plug's thermal range is calibrated to prevent both cold fouling and pre-ignition under sustained load or high-RPM driving. The robust construction and consistent gap tolerance ensure repeatable ignition timing, reducing cylinder-to-cylinder variation and the misfires that plague worn or substandard plugs.

Mechanics and enthusiasts choose the NGK Spark Plug Stock 4764 for routine maintenance intervals, engine rebuilds, and performance diagnostics on a broad range of vehicles where OEM or OEM-equivalent spark plugs are specified. Installation is straightforward—remove the old plug, gap-check if necessary, and torque to manufacturer spec—making this an ideal upgrade for do-it-yourself tuning. Lightweight at just 0.15 lbs, a complete set fits easily in your toolbox, and bulk purchasing allows you to keep spares on hand for immediate replacement when performance monitoring detects early wear or deposits.
