Thought i would mention this as a general interest subject,as i have owned
many many makes of classics all with different tool kits, some better than others.
The factory Pagoda spark plug wrench, is a very good tool , but for a few reasons i will mention
a better wrench , is a 70s 80s Porsche klien ,same size 21mm, for model Porsche 944-928.
It is 11.1/2 inches long ,that is 3.1/2 inches longer than the pagoda wrench, this alloys you
to remove plugs easyer especially alloying you free access up around and above all accesories,
oil dip stick,hoses, etc, etc, especially if engine is hot.
It has a better retaining spring,a little more firmer, and also the rubber insert to hold plug while lifting,
and the 10mm hole for brace is the same size, so also fits.
i never use my original tools anyway, but i do use this Klien as its superb.
They are available for sale used always. regards.
