Be sure to read though before starting, to make sure you have all the necessary tools to complete it.
notes
- when tightening the spark plug use a torque of 25 Nm or 18 ft-lb
now i just retighten the new plugs to about the same feel as the old ones, because i didnt have a torque wrench. i have had not had any problems
- a spark plug socket would be nice and easy, but not necessary
Step 1:
disconnect battery using a 10mm wrench or socket. -always a good idea to remove power while working on the engine. plus once you are done, reconnecting the battery will reset the ecu. w/ fresh plugs in.
Step 2:
remove engine plug cover. use a phillips head screwdriver or a 10mm socket
Step 3:
remove spark plug wires and unplug wire harness - use a 10mm socket to remove the 3 screws on the plug
note: the plug wires are set in good. meaning its gonna take some effort / pull to get the wires out. dont be afraid - yank on them
after plug wire removal you can see the spark plugs set deep in the engine block
Step 4:
you will need a deep set socket with extension to reach the spark plug in its location. i used size 13/16 deep well socket to reach and unscrew the plug.
you can use this weird looking thing in bototm picture, or some source of magnetic stick. Or if you get an specific sparkplug socket than you don't need any of this because that socket will have an ruber thingy inside to grab the spark plug O0
Step 5:
replace your old spark plugs with new ones
i have read that its recommended to replace your spark plugs every 6 months if you run your car hard. i used the cheap, but effective NGK BPR7ES as easy replacement
Step 6:
put everything back together, reconnect battery and feel the difference. it amazes me the simple changes that you can do to this vehicle to see or feel it running
torque your plugs (recommended) 25 nm or 18 ft-lb
