These are the spark plugs originally equipped on the ZC33S Swift Sport. They were used for 5 months and 1,150km from the time the car was new in March 2024. The vehicle was also in its original condition during use. There were no problems, but they were removed to be replaced with aftermarket parts. After removal, they were stored indoors in a box. They will be shipped using the NGK premium RX box for packaging. Please understand. Instant purchase is welcome. Thank you for your consideration.
