BOSCH Spark Plugs FR7NPP332 Double Platinum Set of 6 These are used spark plugs, having been used for approximately 5000km after being newly installed. I replaced the ignition plugs at the same time as I replaced the coils for preventative maintenance. Since they have only been used for about 5000km, it's a waste to throw them away, so I'm selling them. Please check carefully as there is some carbon and oil residue. They were working without any problems. The manufacturer recommends changing them every 20,000-30,000 km, and BMW recommends changing them every 100,000 km. I think they can still be used for a while. 1 Series, 3 Series, 5 Series E88 E82 E90 E91 E92 E93 E60 525i 323i 325i 330i
