This kind of falls under that old saying "if it ain't broke, don't fix it".
With todays vehicles we have fuel injection and computerized ignitions, and that most likely contributes to the longevity of the spark plugs.
The company I worked for had vans that went over 100,000 miles without replacing plugs, and they started and ran perfectly in extreme temperatures.
But every vehicle is different, and your may require new plugs right away. When it starts running poorly, then is the time to start looking for remedies.
Obvious benefits are it will start better and get better fuel economy.

Benefits Of Changing Spark Plugs

It is fairly easy to do yourself. Changing the plugs is easy...hard part for you may be if they are hard to reach or if there are brackets in the way that have to be removed. Change the plugs when the engine is cold. Remove the old plug, double check the spark plug gap on the new plugs, and install them. If they are somewhere hard to reach get a 12" long piece of vacuum hose at the parts store that fits tight over the end of the plugs and use that to twist the plugs in. Make sure you put a little dab of antisieze on the plug threads before you put them in. A lot of parts stores like Autozone loan out torque wrenches with a deposit. You might not be able to get to all of the plugs with a torque wrench...just torque one down and get a feel for how tight it should be by undoing it by hand and then do the others by hand. If you are going to be trying some of your own maintenance then buy a Haynes, Chiltons, or other repair manual off of eBay before you start. Also, the antisieze they sell in the little packets at the counter of the parts store costs about as much as a big tube down the aisle. After you buy those things the cost may not be a great savings over having it done on the first car but after that you'll have the manual to help save on future repairs. With those miles new plugs will probably help.

There is a recommended change interval probably in your owners manual. Over time spark plugs deteriorate from producing the spark When this happens it changes the spark plug gap causing irregular spark and missing. You don't have to wait to change them. When you do change them. Wait for the engine to be cold. Don't change them when the engine is hot or warm because it could cause you to cross thread it by putting a cold spark plug in an heated up expanded hole. Check on the sticker under your hood. It should specify the proper spark plug gap that you need to gap the new plugs to.
If the plugs come with a little crush gasket thread it into the hole by hand a tight as you can with no tools or a socket not attached to a ratchet, Then go 3/4 of a turn tighter with a ratchet attached.
If it doesn't have a crush gasket then tighten it as tight as you can like before with no tools and turn it 1/8th of a turn more with a ratchet. this will keep you from over tightening them,

All vehicles have a recommended service schedule which includes changing spark plugs at around 60,000 miles.
Plugs should be changed even if there are no noticeable problems. Decline in engine performance is slow, and we tend to adapt to it. You should notice a difference in your vehicle after changing the plugs. It is also a good idea to change the ignition wires while you're at it.

It depends on the model and type of plugs used. Even if they are titanium or platinum plugs, I would have them checked every 50,000km/ 30,000 miles. It keeps the threading and wells of the spark plugs from carbon build up. When it is time to change the plugs it makes it easier to replace them.

depends on the car and year, just drive it until it starts running bad and then take it in :)
