海拉空气流量计22204-30010（197400-2110），丰田海拉克斯/雷克萨斯精准进气测量KLP

Hella mass air flow sensor 22204-30010 (197400-2110) directly replaces Toyota OEM 22204-30010; broad compatibility with Toyota Hylux and later Lexus models. Core function: accurately measure intake air mass and feed data to ECU to ensure proper fuel injection and ignition timing; resolves idle instability, acceleration weakness, and high fuel consumption, particularly for restoring power in older vehicles. If starting is difficult, exhaust emits black smoke, or check engine light is on, it usually means the MAF sensor aging; replacing can save fuel and hassle.
