[alfa] Re: alfa-digest V10 #69 Indexing spark plugs

["George Schweikle" <schweikg@xxxxxxxxxxxxx>]

Jon,

It isn't necessary to buy additional plugs to get the correct index. Go to
your local automotive performance shop, and get a set of spark plug indexing
washers. These come in varying thicknesses, and can be used to get the plug
electrodes aligned to clear the valves.
