Known for their precision engineering and long-lasting performance, Bosch plugs are trusted by professionals and DIYers alike. Model: Bosch 6241 (Replaces FR7DCX). Quantity: 4 spark plugs (complete set).
These worked fine on my '99 olds with a 3.8L V-6, as they were listed in car's specs as being the right plugs. Don't know why seller thought they were only for a '93 Cadillac, the HR9DPY is a common plug for lots of other vehicles. Granted, the way plug manufacturers name them doesn't help.
