SOURCE: 2006 Toyota Tacoma Low Mileage or Not...Spark Plug Life

24 mpg on the highway is actually pretty good for that truck. at 48000 miles and being 3 years old its time for plugs, air filter, and fuel filter if available. thats cheap maintenance for now. but if very self conscious, run some fuel injector cleaner first, then change the plugs, because any octane booster or fuel injector cleaner can run the risk of fouling out a plug, by creating a hotter spark then what, normal gas does. the burn is hotter.

You need a special tool when they are stuck on, it's like a long pair of neddle noise plyers with sides that grabs the wire by the boot evenly, but twist them loose from the plug as you pull the rubber actuaully melts itself to the plug sometimes

Locate the spark plug cover on the engine.On some Toyota Tacoma engines, the cover is across the top of the engine. On others, it is along the side 4 cyl. Remove the cover to reveal the ignition coils and spark plugs wires. The spark plug wires are plugged directly into the engine and the ignition coils are in the tip of the spark plug wire.
Remove the coil and wire from the spark plug. Twist and pull the plug out of the engine. Remove the spark plug from the cylinder well with a socket extender and socket wrench. Turn the wrench to the left to unscrew the spark plug from the engine.

Discard the old spark plug and apply a coat of anti-seize compound to the threads of the new spark plug.

Insert the new spark plug into the socket. Use the socket and extension to screw the spark plug into place.

Return the ignition coils and spark plug wires to the engine and turn it to lock the plug in place. Repeat the entire the process with the remaining spark plugs.

Replace the spark plug cover when all of the spark plugs are replaced.

Good luck and hope this helps and The spark plug tension may range between 11 and 15 foot pounds, depending on the size of the spark plug. The correct tension is indicated on the spark plug's packaging.
