How often should the spark plugs be replaced in an 8th generation Accord?
2 Answers
8th generation Accord's spark plugs have different replacement intervals depending on the material: ordinary copper core spark plugs should be replaced every 30,000 kilometers; yttrium spark plugs every 50,000 kilometers; platinum spark plugs every 80,000 kilometers; iridium spark plugs every 100,000 kilometers; and platinum-iridium alloy spark plugs every 120,000 kilometers. The 8th generation Accord is a car under Honda Accord, with a length of 4945mm, width of 1845mm, height of 1480mm, and a wheelbase of 2800mm. The front design of this car is more heroic, with angular headlights, an air intake grille, and flared fenders, showcasing a dynamic and capable temperament. Particularly, the waistline running from the front to the rear of the car body resembles a stroke in Chinese calligraphy—powerful yet dynamic.
I've been driving my 8th-generation Accord for seven years now. The owner's manual recommends replacing spark plugs at 100,000 km, but actual replacement should consider driving conditions. With mostly city commuting, I noticed significantly slower cold starts at 80,000 km - the improvement was immediate after replacement. The mechanic explained that frequent short trips accelerate carbon buildup, suggesting earlier inspections. Replacement is advised if the electrode gap exceeds 0.9mm or the ceramic insulator shows yellowing. Additionally, older spark plugs in northern winters often cause hard starting. My personal advice: don't delay replacement too long, as hidden fuel consumption increases will outweigh any temporary savings.
