丰田花冠 点火线圈 90919-02238 高效燃烧提升动力

When Toyota Corolla experiences idle instability, acceleration hesitation, engine shake, or warning lights, the ignition coil may be aging or ruptured, resulting in insufficient ignition energy and incomplete combustion. This part converts low voltage to high voltage to ignite each cylinder’s air-fuel mixture, ensuring smooth operation and power delivery. OEM number 90919-02238; fits many 1.6L/1.8L four-cylinder Corolla engines (2004-2013). Important: disconnect the battery negative before work; replace in ignition order; ensure high-voltage lines or coil plugs are fully seated to avoid misfires.
