you will need
8mm
10mm
5/8 spark plug socket
3/8 ratchet
3/8 extension (it could be 4in and longer)
and spark plugs factory plugs are pregap iridium
spark plug torque is 13.0 lb.ft
coil torque 8.7 lbf.ft
spark plug part # NGK 1zfr5k-11
# DENSO pkj16dr-m11
and spark plug anti seize on spark plug thread
what you need to do is remove the plastic cover 8mm socket or 10mm sockets
now remove the spark plug covers and remove the spark plug coils too 10mm head bolt you will need a 5/8 spark plug socket and a 3/8 ratchet and a 3/8's extension too
you need OEM spark plugs they work the best
hope this will help

FIRST OF ALL YOU HAVE CHANGE SPARK PLUGS WHEN ENGINE IS COOL.IF YOU CHANGE THEM WHILE ENGINE IS HOT YOU COULD DAMAGE THE ALUMINUM HEADS OR CAUSE DISTORTION.TO CHANGE SPARK PLUGS YOU NEED A SPARK PLUG SOCKET.A TORQUE WRENCH.ITS NOT MANDATORY.BUT IT WILL KEEP YOU FROM OVER TIGHTEN SPARK PLUGS.YOU NEED A 3/8 RATCHET AND EXTENSION.YOU ALSO NEED A SPARK PLUG GAP GAUGE.AND SPARK PLUG BOOT PULLER.YOU ALSO NEED SOME ANTI SEIZE COMPOUND.TO PREVENT DAMAGE THREADS WHEN INSTALLING THE SPARK PLUGS.

ALL YOU NEED IS 3/8 RATCHET WITH A 5/8 SPARK PLUG SOCKET.YOU NEED EXTENSIONS AND UNIVERSAL JOINTS TO GET TO HARD TO REACH PLACES.YOU NEED A SPARK PLUG GAUGE.YOUR SPARK PLUG GAP SETTING WILL BE. 0.060 THAT WILL BE FOR THE 2.2 AND 3.1 ENGINES.

If you are going to change your spark plugs, make sure you use platinum spark plugs over the regular ones. Here's why:

Follow the spark plug wires down into the engine, a soft tug should pull the wire loose from the plug and then you will need a spark plug socket to change them.
