NGK Spark Plug Stock # 1134

The NGK Spark Plug Stock #1134 (BR8HS-10) is a standard resistor spark plug engineered for reliable ignition performance across a wide range of automotive applications. This 14mm threaded plug features a 0.490-inch reach and gasket seat design, making it a direct OEM replacement for countless vehicles that depend on NGK's proven firing characteristics and proven longevity in the field.

The resistor element integrated into this plug design suppresses radio frequency interference, protecting vehicle electronics from electromagnetic noise that can degrade performance or trigger diagnostic trouble codes. The gasket seat provides a secure seal within the cylinder head, preventing combustion gas leakage and ensuring consistent spark timing under varying engine loads and temperatures. With a reach of 0.490 inches, this plug sits at the correct depth to maintain optimal electrode gap exposure to the combustion chamber without fouling or creating dead spots in the firing sequence.

NGK spark plugs are specified by original equipment manufacturers because their manufacturing tolerances, materials, and thermal range are calibrated to match OEM engine maps. The BR8HS-10 is the correct fitment for vehicles requiring a 14mm plug with standard reach and resistor technology. Mechanics and vehicle owners performing routine maintenance or addressing starting issues, misfires, or poor fuel economy often find that spark plug replacement with an OEM-spec NGK unit restores baseline engine performance. This plug is sold individually, allowing replacement of a single worn unit or staged replacement across a multi-cylinder engine.
