Spark Plug. Buick Roadmaster 1996

For 1990-2009 cars

Caution: Wash your hands after handling coated spark plugs and before smoking. The coating is a non-hazardous material and incidental contact will not cause any adverse effects. However, exposure to polymer vapors - the result of contamination of cigarette products and subsequent burning of the polymer - may result in flu-like symptoms and should be avoided.

Platinum-tipped, resistor-type, tapered-seat spark plugs are used on the engine. No gasket is used on these tapered-seat spark plugs. When replacing spark plugs, use only the type specified. Normal service is assumed to be a mixture of idling, slow speed, and high speed driving. Occasional or intermittent high-speed driving is needed for good spark plug performance. It gives increased combustion heat, burning away carbon or oxides that have built up from frequent idling, or continual stop-and-go driving.
