BIG difference to your C3s
Which is easier to change the spark plugs

Thing is........most C8's sold here in the UK will be through the 'official' dealer (just the one) and under 3 year warranty.......so owners won't be touching anything in the engine (except perhaps to wipe of a few spec's of dust, fly crap or water marks.......guess with long life spark plugs it'll be a good few years before owners will even think about a 'home' service........
