Is it necessary to replace the spark plugs with original ones for a Corolla?

Generally speaking, ordinary spark plugs need to be replaced every 20,000 kilometers, while platinum or iridium spark plugs can last up to 60,000 kilometers or even longer before replacement. Spark plugs: Spark plugs are crucial components of the ignition system in gasoline engines. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Corolla: The Corolla, formerly translated as "Huaguan," is a brand under Toyota Motor. The Corolla is equipped with Michelin 215/45R17 tires, high-performance shock absorbers, TRD-TF4 17-inch sport rims, reinforced clutches, and high-performance brake pads, ensuring it has relatively ideal sports performance.
I've been driving a Corolla for several years, and spark plugs have a significant impact on engine ignition. The original parts are specially designed by Toyota, offering high compatibility, faster starts, and stable fuel efficiency. If you opt for non-original parts, such as NGK, they may be cheaper but could have non-standard specifications. If installed improperly, engine vibration might increase. The Corolla manual recommends replacing them every 60,000 kilometers. I always choose original parts to ensure safe driving. However, if you're on a tight budget, carefully comparing specifications from reliable brands can work, just don't cut corners to the point of causing headaches. Regularly checking the condition of spark plugs is key; otherwise, it can affect overall performance.
As a budget-conscious car owner who uses a Corolla for daily commuting, I've tried every way to save money on spark plug replacements. The OEM ones are significantly more expensive but offer stability and reliability. After switching to third-party brands like Denso, I noticed slightly slower starts but no major issues. The key is ensuring compatibility with your model—don’t buy blindly. With the Corolla’s long maintenance intervals, the savings can go toward oil changes or tires. But remember, if your car is under warranty, using non-OEM parts might cause headaches—a friend of mine got denied service for this reason. Overall, OEM isn’t a must unless you’re chasing that perfect driving feel.
I'm a new Corolla owner, just driven for a year and a half. Genuine spark plugs are absolutely essential, especially since the warranty manual emphasizes using only Toyota parts, otherwise the manufacturer's warranty could easily be voided. Spark plugs may be small, but they affect starting and fuel consumption; I once tried using substandard ones and the engine light came on, which was terrifying. The Corolla is well-designed, and genuine parts fit seamlessly—safety first. If it's past the warranty period, then consider alternatives, but it's too early now, so just stick with the recommended ones. Remember to check them during every maintenance service—don't wait until problems arise to regret it.
