Product ReviewsFord Sierra 1.6 Accuspark , Copper Spark Plugs AF7C, F7YC, AP6FS

Amazing plugs for old Stationary Engines

Purchased for use in a lister stationary engine as they are an 18mm thread. I don't know why but these plugs make the engine run much better, firing on every stroke, and are for more reliable for starting. Have tried in other single cylinder stationary engines with the same good results. Very good value too compared to other spark plugs.Read full review...

Good plug for EDIS "Wasted Spark" Ignition.

I'm only giving four stars because only time will tell how they will perform.
I've used them before but they suffered from short runs and a rich mixture during work on the vehicle so not a fair test,
The three ground electrodes are of little use for normal use but they do make a difference for an ignition system using a coil pack and "Wasted Spark" this is where two plugs fire at once, the plugs being in series so one of the plugs will be of incorrect polarity with the spark traveling from a ground electrode to the centre electrode.
Looking forward to testing the plugs with the correct mixture and some longer runs.
