It is important to have your Lexus’s spark plugs replaced at the recommended service intervals for best performance and fuel economy. Over time, spark plugs become fouled with glaze caused by a combination of engine deposits and fuel. Glaze decreases the spark plug’s ability to conduct electricity, which means that the engine has to put out more power to get the same amount of fuel burned. When a spark plug becomes worn like this, it can also change in shape enough to fall out of its hole in the head or cylinder bore and foul the even number cylinder on V8 engines. Toyota recommends replacing the spark plugs every 100,000 miles. It’s not hard to do and can be done in less than an hour, sometimes even less. The process only involves removing a couple of easy-to-reach nuts and the old plugs. If you have a manual transmission your job is a bit easier. If you are replacing the plugs yourself, within 30 minutes of work are required.
