Tune up

It should only take someone with basic automotive skills about an hour and a half to replace the plugs. Just make sure the engine is cold, you use ONLY OEM parts, and don't "drop" the plugs into the hole. Use the boot off an old spark plug wire or a spark plug socket with a rubber grommet on it to hold the spark plug so you can place it in the hole nicely. You don't want to risk cracking a plug or closing the gap. Most OEM plugs will come pre gapped. But I check the gap anyways just to make sure it's right. You will find the correct gap on the Catalyst sticker found under the hood. The fuel filter is in the tank. I wouldn't recommend replacing that yourself. Best of luck
