I would greatly appreciate help understanding all the needed parts when replacing ignition coils on a honda fit 2007.
My understanding is it is best to replace all 4 (are there 4 total?) as well as the spark plugs - also 4?
What other parts are needed, does this car require spark plug wires?
Basically if anyone would have a few moments to list all recommended parts that would be wonderful. Would this be a good time to replace air filters as well? Car has 116K miles.
