Oh, sorry about that. Mazda doesn't call for anything other than a oil/filter change at 15k. Don't even need to change the plugs till 75k, although I wouldn't wait that long. They call for the air filter to be changed at 30k. These are for normal driving conditions. Are you a man or a woman? If you're a man, you shouldn't own a car without being able to change your own air filter and spark plugs. Right now there's no need for it, but if you feel like tinkering around, go for it, plugs and filters are cheap enough.
