Changing spark plugs on a Boxster is easy; I would be very surprised if a shop refused to replace them at your request. I am guessing your Boxster as a daily driver so spark plug replacement is not as critical as someone that drives theirs on the track. My Boxster is a daily driver and I have gone well past 60k miles on a set of plugs with no issues. Currently I have 232,000 miles on my 986 and have changed the plugs three times in the last 200,000 miles. Have you thought about replacing the plugs yourself?
