How do you change a spark, in terms of difficulty - if you got the right tools it is easy. First off, a round of inspection on the engine block:


To remove the spark, we got to remove coil packs, first off .. lifting the connector and disconnect the cable by pulling it out.

Twist the coil pack clockwise and anticlockwise to loosen it and pull it out. Remember that this step must be done when engine is completely cold else you wont be able to pull it out due to the heat expansion.

Unload coil packs, doing 1 at a time.


Inspect the coil packs.. if it is severely oxidized at the connector to the spark .. it is time to change the coil packs.

You need this tools to unlock the sparks, to the right is the OEM bi-hex 14mm required to remove the oem plugs. On the left is the 16mm hex tool for the iridium sparks plus some other ratchet kit i got to get it done. The extensions are required in order to reach the plugs installed inside the engine.


Now just fix the spark socket to the ratchet and reach for the plugs. Turn counterclockwise to remove ..until it is loose, then slowly lift up the spark using the socket. There is a catch within the spark socket, so make sure it is correctly seating on the spark before removing else you will drop the plug. If you drop it, you may need to check the gap again. As now we have direct access to the engine chamber .. it will be wise not to drop anything inside the engine else you will earn a visit to the SC with the toll truck.


The next step is just use the hex spark socket, ensure that it it seating properly holding the plug, slowly insert in and tighten until snug. Rules of thumb is to tighten using hand lightly until snug, then tighten for another 1/4 turn. DO NOT OVER-TIGHTEN ELSE YOU RISK DAMAGING THE THREAD. Our EP6DT is a aluminum block, be gentle with it.

Does it matter .. hell yeah .. after new plugs and smaller gap .. i did not had any misfiring so far ..
so keeping the gap and sparks clean does help.

Got out the old plugs to clean and regap as well. It is as easy as light tapping the ground on concrete ...
