How to Replace the Spark Plugs on a Toyota 4Runner

Model: Toyota 4runner N210 - Years 2002-2009
Part: Spark plugs

To replace the spark plugs on a Toyota 4Runner, open the hood to remove the plastic cover on top of the engine block. You will need to remove the air filter box first. Once you have access to the engine block, disconnect the connectors attached to the coils to pull them out and access the spark plugs underneath. After removing the old spark plugs with a socket wrench, install the new ones and reassemble all the components you removed.
