The spark plug gap setting for a 1992 Buick Roadmaster with a 5.7-liter engine is typically between 0.040 to 0.060 inches (1.0 to 1.5 mm). It's important to consult the vehicle's owner manual or service manual for the most accurate specifications, as gaps may vary slightly based on the specific engine configuration. Always ensure that the spark plugs are properly gapped before installation for optimal performance.

On a 1996 Buick Roadmaster, the spark plugs are located on the engine's cylinder heads. This vehicle typically has a V8 engine, so you will find the spark plugs on either side of the engine, beneath the ignition coils and covered by the engine's intake manifold. To access them, you'll need to remove the ignition coil packs and possibly the intake manifold, depending on the specific engine configuration.

Yes it needs spark plugs and wires. I own a 1992 Buick Roadmaster and had to replace plugs and wires recently. Not that expensive, I bought AC Delco plugs and wires. I had a discount as well. Be sure you know what your doing, which one is which I change them one at a time so not to mix up wires and the last on on the left side is a pain, the last two. Change them every 50,000 miles. Or less.
