Step 1

With the engine off and cold, open the hood & locate the air filter, the spark plugs, ignition coil (or coil pack) and the distributor cap and rotor (if applicable). These are the parts most commonly replaced when performing a basic engine tune-up.

Step 2

Locate the airbox and release the airbox clips or remove screws and remove the air filter box cover. Remove the air filter.

Step 3

Vacuum first, then wipe out the air filter box to remove all debris. Install the new air filter and re-install the filter box cover.

Step 4

Grab the spark plug wire boot and remove the wire from the plug. Remove the spark plug from the cylinder head using a ratchet, spark plug socket, and socket extension.

Step 5

Check the gap on the new spark plug and adjust as necessary to specification.

(Heres a link for checking spark plug gap)


Apply a small amount of anti-seize compound to the plug threads. Thread the new spark plug in by hand and then tighten it to the recommended torque with a socket and ratchet / torque wrench. If necessary, you may use a length of vacuum hose to help the spark plug installation into the threads. Reconnect the spark plug wire. Repeat for the rest of the spark plugs.

Step 6

If applicable, remove the distributor cap with the wires attached. Replace the rotor and install the new cap. Transfer the wires from the old cap to the new cap one at a time. Do not mix up the wires.


Hopefully now you have a good understanding of performing a basic engine tune.
