So I left the Camera at home and I didn't get to do the DIY for you guys. I'm just trying to break it down to show you how easy it is.
I guess this would be a more advanced DIY since I'm not really showing you what I did. but it's basic common sense right in front of your eyes.
I bought the newly released NGK spark plugs to replace the OEM factory Denso spark plugs.
Tools:
10mm Socket-----RED
12mm Socket-----BLUE
12mm Wrench-----BLUE
5mm Allen Key-----GREEN
Intake Mani. Gaskets (3 Pairs)-----YELLOW
Extension
Spark Plug Socket or 16mm Socket
I've marked the pictures with certain colors as to what tool you will use.

after you remove that there should be connectors attached to the spark plug tubes. remove those. each tube has a 10mm bolt holding it down. remove that. then use your extension and spark plug socket to remove your spark plugs.
hope this helps!
sorry in pic 5 it says look at pic 4 for reference but it's actually pic number 1. pic 4 was the file name :X

this took me about an hour and a half cause I didn't really know what to do at all. and that 12mm bolt behind the manifold is a BEEEECH
I have about 67k miles on my car. My OEM stock Denso plugs were still pretty good. so those who debate on changing them at 60k or 100k.. they will last till a 100k np IMO. I just like to change stuff out early to make the car last
just like how I change my oil every 3k with synthetic when it's not necessary and can last till 5k. lol

Haha trust me i looked for all kinds of shortcuts. YOU DONT HAVE TO TAKE OFF THE INTAKE. Just force the wires out the way to give you clearance for the left side (passenger side). But as for the drivers side. Theres no way in hell you can get the middle spark plug cause theres no room to pull the tube thing because the stock manifold is in the way
