Update: just changed the spark plugs.
I was going to take pictures to document it, but didn't think there is a need. It's pretty obvious on what needs to be moved aside to access the spark plugs and coil packs.
Just a couple of tips:
- Front spark plugs on both sides are easily accessible, no problems.
- Passenger side, definitely need to remove the battery to access the last 2 plugs.
- Driver side, will need to unbolt a fuse box and move it aside to remove the 3 coil packs closest to the firewall. It makes it easier to access as well.
- Tools: I used a magnetic spark plug socket with a built in 6inch swivel + universal joint + 6 inch extender. 10mm socket to remove the coil packs, battery nuts, and fuse boxes that were in the way. Extra long needle nose pliers to remove the connectors from the coil packs. I could not remove them by hand by depressing the tab (confined space.) Torque wrench for the sparkplugs.
Overall, took me 2.5 hours. Not difficult, just the lack of space and figuring out how to access the plugs makes the whole process take awhile.

All the information I received were that the plugs were pre-gapped. So I did not gap them again. I Purchased part number FK20HBR11, which are the same as the OEM plugs that came out. I believe if you purchase genuine Toyota OEM, it comes pregapped (someone correct me if I am mistaken.) I compared the gaps on the new plugs and they were uniform for all 8 (by eyeing it.)

Yes, in hindsight, I should have just brought it to a dealer.
Plugs were $100 total. If I still have the car at 120k miles, it will be to the dealers as I watch them do it. There's always that "back in my mind" that the techs never change the spark plugs and they just charge you for it, so I decided give it go and know that was really done. Plus I guess the satisfaction that I did at least something on the car myself.

Back from the dead, anyone using one step colder plugs? If so which ones, I am only at 70,000km but I am swapping my intake for a ported one this weekend so I might as well do plugs while I am in there. N2O is a definite future possibility so I was thinking of going one step colder now.
