They are a wierd size, and the 5.5mm is correct, but you can also use a 7/32 socket to get them out. I use it all the time. And don't have to he-man them on, just snug will work.
thanks fordman. I was going to try to get that one coil out that i coudnt yesterday and swap with other gtp in driveway (the crap one with over 300k, But never has major issues lol) I used 7/32 to get the rest out. with out issue.the bolted has been totally rounded by past owner so im going to just try to get my multi-tool out a try to cut to get a flat head screw driver in there. or i i mite just get the angle grinder out and cut the whole coil out with screw. but we will see.
again thank you Fordman for the advise! keep it coming
