¥2,000 → ¥1,600 Thank you for viewing. NGK Iridium MAX 3-piece set LMAR7AIX-P (94981) I was using these in my car. How about it for those who want to try replacing the plugs to save money? Registered November 2017 DAA-MM42S Flair Wagon Custom Style XT (Turbo) Used for just under 40,000 kilometers. There were no particular problems, but I replaced the plugs for the second time this time, and these are the ones I removed. They were quite clean, so I removed the dirt with engine conditioner, and then washed them with kerosene and an ultrasonic cleaner. I haven't dropped the plugs, but I haven't measured the plug gap.
