incase something goes wrong with your engine while doing a high boost run and you don't notice, I would rather have a plug go out than my engine. I personally enjoy changing plugs on my Z, hell I enjoy doing anything mechanical on it =) Also gives me a chance to read them and see if everything is in order like z324u said, and I can get them at my local autoparts store.
