Q:how many miles will these sparkplugs last?
jonathan k.
A:BEST ANSWERHi Jonathan, I'm glad to assist you. The replacement interval for spark plugs varies based on the type of spark plug and the vehicle manufacturer’s recommendations. Copper spark plugs typically need replacement every 20,000 to 30,000 miles, platinum spark plugs every 60,000 to 100,000 miles, and iridium spark plugs every 100,000 miles or more. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, 2WD/4WD, and engine size). You can also call our parts specialist (for real-time live & immediate assistance) on our toll-free number, 1-866-529-0412 (Mon to Sun). Show less
