To replace the spark plugs on a Benelli TnT 899, you need to unscrew the bolts securing the seat of the motorcycle and also those securing the fuel tank at the front of the bike. This can then be removed to access the bolts securing the air filter box underneath, which will also be removed. Now disconnect the wires connected to the coils, remove the coils from their seats, and take out the spark plugs using the appropriate socket wrench. You can then install the new spark plugs, reposition the coils and the air filter box, and reassemble all other parts that were removed.
