don't let the name and description fool you it's 8mm wires with 2mm silicone around them which is pretty bad of them for false advertising . in addition, the stopper end is very difficult to hold in place. they come off very easily. They are also much longer than standard heads. So unless you are using at least long pipe heads, don't try as they will touch your head. You need clearance from the headers if you don't want them to be melted. They look like they are good quality but for all that has been said I wouldn't bother changing just the spare and better spark plugs.
