If you say so...
However, I think you are missing the actual point I was making....
That changing the coil pack each time you change the plugs is a prudent practice?
I changed my plugs every 20,000 miles and the coil packs when they failed either from water ingress or heat damage. Basically five or six plug changes for every coil pack failure.
Like I said, you are missing my point.
If you are doing a routine plug change, then there is no need to change either coil pack.
If you are changing the plugs as a result of a misfire, then a change of coil pack should be considered as well. A bad coil pack may be obvious from corrosion, swelling or splits in the plastic.
The actual point was that only changing the plugs to cure a misfire, may well result in having to remove certain parts twice to access 2 4 6 coil pack, if it then turns out the misfire wasn't due to the plugs themselves.
Is that clear enough?
