Where are spark plugs on 1995 Avalon?

On a 1995 Toyota Avalon, the spark plugs are located on the engine's cylinder heads, beneath the ignition coils. You will need to remove the engine cover and the ignition coil assembly to access them. The Avalon typically has a V6 engine, so there will be six spark plugs, one for each cylinder. Make sure to follow proper procedures when replacing them to avoid damage.
