How often should the spark plugs be replaced on a Camry?

[LucyFitz]

The replacement interval for Camry spark plugs is approximately 100,000 kilometers. Spark plugs are a crucial component of the gasoline ignition system, responsible for introducing high-voltage electricity into the combustion chamber, causing it to jump the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. The Camry is a mid-size sedan under GAC Toyota, with exterior dimensions of 4885mm in length, 1840mm in width, and 1455mm in height, and a wheelbase of 2825mm. The Camry is equipped with a 2.0L naturally aspirated engine, paired with a 10-speed continuously variable transmission, delivering a maximum horsepower of 178 and a maximum power output of 131 kilowatts at 6600 revolutions per minute.

I've been driving a Camry for several years, and the spark plugs are usually replaced every 100,000 kilometers. The Toyota manual recommends replacement at around 80,000 to 100,000 miles, which is approximately 150,000 kilometers. The last time I replaced them was at 120,000 kilometers when I noticed the car was starting a bit slower and fuel consumption had increased slightly. After inspection, the spark plug electrodes were found to be worn. If you forget to replace them, the engine might shake noticeably, affecting driving smoothness. Driving habits are crucial—frequent stop-and-go traffic can accelerate spark plug wear, so I make it a habit to have a mechanic check for carbon buildup every 50,000 kilometers. Replacing them doesn't cost much but can save fuel and protect the engine. I believe regular maintenance saves more money than repairs. Checking them yourself is simple—just unplug and see if the electrodes are blackened—but it's best to leave it to a professional shop to avoid hassle.

I enjoy doing DIY maintenance on my Camry, and changing spark plugs isn't too complicated. Toyota recommends replacement around 100,000 miles, but I take them out to inspect every 60,000 miles. Using a feeler gauge, the normal electrode gap should be 0.8-1.0 mm. If the wear is excessive, it's time to replace them with new parts—all you need is a socket wrench set and it only takes a few minutes. Failing to replace them in time can lead to poor ignition, increasing engine fuel consumption or causing excessive exhaust emissions. Remember to disconnect the battery before DIY work—safety first. Opting for OEM spark plugs ensures better durability. Driving conditions play a big role; highway driving allows them to last longer, but frequent stop-and-go city traffic accelerates aging. Regular inspections save hassle and repair costs.

Don't delay changing spark plugs. My decade of driving a Camry taught me that replacing them at 80,000 km is safest. Toyota recommends 100,000 km, but aged plugs affect starting and acceleration. I've seen engines misfire from prolonged delay, costing big repair bills. Check them during biennial maintenance - replace early if electrodes show erosion or heavy carbon buildup. Always use quality spark plugs to ensure ignition efficiency and prevent unexpected stalls.
