NGK 7637 B8HS-10 标准火花塞 经典替换型号稳定可靠

NGK 7637 B8HS-10 standard spark plug is a classic replacement model; although it has no direct OEM number, it offers strong universal compatibility and can replace most OEM plugs for post-2000 vehicles. It ignites the air-fuel mixture to ensure stable engine operation and improved combustion efficiency, mainly suitable for General Motors brands and some Japanese and European models. After installation, it can solve starting difficulties, hesitation on acceleration, and high fuel consumption; if rough idle, reduced power, or delayed ignition occur, the spark plug has aged.
