Spark plug required is Denso #SK16HR11 with 19Nm (14lbs ft) torque. Remove 10mm nuts and bolts for engine cover, coil pack and battery terminal. Coil pack connectors are very fragile. Use 16mm spark plug socket with 3/8" or 1/2" ratchets.
When disconnecting the battery, minus terminal first When connecting the battery, plus terminal first. Use Denso or NGK only. Toyota coil pack connector is rather fragile. So, just remove the bolts and pull all the coils out together without disconnecting the connectors.
Tools & torque
1. Spark plug torque is 19Nm (14lbs ft)
2. 10mm nuts or bolts for engine cover, coil pack and battery terminal
3. Torque wrench, 10mm socket

Details
- Disconnect the battery, minus first and then positive terminals
- Remove the engine cover, two 10mm nuts or just 3 grommits.
- Remove 10mm bolt to remove coil pack.
- Extreme care in disconnection will be no good. The clip just would breake.
- 16mm (5/8") Spark plug socket to remove the spark plugs. Just 5" extension is good enough.
Note. Toyota coil pack connector is rather fragile. So, just remove the bolts and pull all the coils out together without disconnecting the connectors. That is an option as well, use your own judgement.
Coil gasket should be removed as well. Coil order does not matter. Some recent models need 14mm socket with 8mm coil pack nuts. Genuine spark plugs come with pre gapped.
