Where is spark plugs located on 2006 Toyota Tacoma and how do I replace them with new ones..?

On a 2006 Toyota Tacoma, the spark plugs are located on the engine cylinder head, typically under the ignition coils. To replace them, first, disconnect the battery and remove the ignition coil by unscrewing the bolts and pulling it out. Then, use a spark plug socket to carefully unscrew the old spark plugs and replace them with new ones, ensuring they are properly gapped. Finally, reattach the ignition coils and reconnect the battery.
