2 Answers
Toyota Corolla Hybrid spark plugs should be replaced every 100,000 kilometers. The types of spark plugs include: 1. Standard spark plugs; 2. Insulator-tip spark plugs; 3. Electrode spark plugs; 4. Seat-type spark plugs; 5. Multi-electrode spark plugs; 6. Surface-gap spark plugs. Taking the 2020 Toyota Corolla Hybrid as an example, it belongs to the compact car category with body dimensions of: length 4635mm, width 1775mm, height 1470mm, and a wheelbase of 2700mm. The 2020 Toyota Corolla Hybrid features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.8L naturally aspirated engine producing a maximum horsepower of 99PS, maximum power of 73kW, and maximum torque of 142Nm, paired with an electronic continuously variable transmission.
I've been driving a Toyota Corolla Hybrid for two years now, and generally, the spark plugs need to be replaced every 100,000 kilometers or so. During my last maintenance visit, the technician showed me the manual, which clearly recommends that the ignition system in hybrid models is more critical than in conventional cars because the engine starts more frequently, leading to faster wear on the spark plugs. If not replaced in time, the car may become harder to start, fuel consumption could increase, and engine vibrations may become more noticeable, especially in stop-and-go traffic. What worries me more is the safety aspect—if the ignition fails on the highway, it could be a big problem. So, I have the spark plugs checked every 50,000 kilometers to ensure there are no issues. Replacing the spark plugs isn't expensive, costing around a thousand yuan, but it ensures smooth operation and long-term durability. Always refer to the user manual for the most accurate guidance—don’t wait for problems to arise before taking action.
