Under the hood of your car, you should see 4, 6, or 8 spark plug wires running to the sides of your engine depending on how many spark plugs your car has. These cables hook onto the tops of the plugs. Pull the caps off. Underneath, you will see the top of the plugs. You will need a special socket to remove them. This socket is usually standard with most socket and ratchet sets.
Take your old plugs out. Make sure you use a gap setter to set the gap on your new plugs. And make sure you know the correct gap setting for your vehicle. Put the new spark plugs in 'hand tight'. Just put them in by hand and them give them about 1/4 turn with your ratchet. Put the wires back on. It's that simple.
You can get a gap setter at any decent auto shop and they can look up the setting for you. If need be, they should also be able to point out where the spark plugs are.
Nissan Sentra's have factory-installs 'ND', or Nippondenso spark plugs. You can use Autolite, Bosch, Champion, or NGK spark plugs for Sentras.

After 105,000 miles. Nissan Maxima spark plugs are platinum-tipped and lasts for many years.
