408 spark plugs

Off the top of my head I don't recall what plugs I went with but, to get them out all you should need to do is get a socket on there (I use a 3/8" drive deep well with a short extension ..and yeah, it's a SOB to get the exact right configuration to reach - and it's probably different for both!) and just get them to crack loose, then a piece of rubber hose (like what comes inside a spark plug socket) over the tip should allow you to spin it out by hand... the trick is getting them back in. You've been warned. :lol:
