does anyone know where i can find the DIY to change out sparks plugs? i remember seeing someone do a write up on a black 3rd gen TL but cant see to search for any DIY.

 

There doesn't appear to be a DIY of replacing spark plugs. Perhaps you should make one.

 

Description available in new Haynes repair manual (#12050). Remove engine cover and ignition coil cover. Remove plugs. Reverse. Usual notes: Keep dirt out of plug holes, use anti-seize compound, firmly seat coil, etc. Seems simple enough. Good luck.

 

Its pretty straightforward...
Tools Needed:
Flat head screwdriver
Hex set
5/8 socket
3/8 extension
3/8 Ratchet

1. Pull off the Plastic cover with the flat head
2. Unplug the coil packs
3. Pull off the strut bar (Optional I pulled it off because it was easier for me to get to the rear plugs they were sex 10mm or 12mm I forgot)
4. Pull the coil packs out (use the hex set to loosen the one bolt holding them in)
5. Use ratchet/extension/socket to pull the plugs out
6. Apply antiseize on new plug threads
7. Reinsert plugs (DO NOT DROP THE PLUGS INTO THE SPARK PLUG HOLE)
8. Tighten them up snug
9. Reconnect all the plugs
10 Reinstall strut bar (If removed)
11. Put back on plastic piece and you should be done.
