Set of 6 Spark Plugs
This plug fits many older American cars from the 1960s - 1990s, especially those with big naturally aspirated V8 or V6 engines that originally used the UR4 plug. Examples include:
Buick: Century, LeSabre, Regal, Riviera, Roadmaster (various years ~1980s–1991)
Cadillac: Brougham, Fleetwood, Commercial Chassis (’80s–’93)
Chevrolet: C/K series pickups (C10, C20, C30), Camaro, Caprice, Corvette (’80s–’92)
Other Classic Vehicle Fitments: Electra 225 with big V8 engines, early El Camino models, and similar platforms.
These vehicles often had large displacement V8s where the UR4 heat range and M14 plug were common OEM equipment.
