Based on the search results, the BP6ES spark plug fits a variety of vehicles. The NGK BP6ES plug is commonly used in Toyota Corolla and Honda Civic cars. It is listed individually for R33, in a set of 4 for R106 from Autoshop, and in a bulk pack of 10 for R360. I would recommend the Autoshop set of 4 for R106 as it is a good price and you will have spares on hand. Let me know if you need any other details on fitting or specifications. I unfortunately don't have access to confirm every vehicle type, so checking your owner's manual is best to verify it is suitable for your specific car.
