who can I find to change my spark plugs?
So I use torco octane booster regularly given I only get 91 octane pump where I live and have no access to race gas. I have 8k on the clock now and anticipate the plugs turning orange quite quickly. I would like to change them every 15k or so to keep the spark going strong since I have read the orange coloring does not effect function unless you go very long times without changing them.
Problem is I do not want to go to the dealer obviously! Can any indy shop be able to do this if I provide the spark plugs quite easily? Or is this something I should be finding a really reputable and skilled shop?
