Bill, again it is a trust issue. He can tell you that he has to do a partial engine drop.. Myself, I take the right rear tire off and remove the rear tin/shield.. It helps if you reduce your magnetic plug socket down to a 1/4" drive with a healthy extension.. Marking the new set of plugs will allow you on the removal to see if...

1) The mechanic that you handed them actually installed them???

2) Recent mechanic did 5 plus a reach in the drawer action...

 

Those spark plugs look like they are coming from this part of the world Over here I would be surprised if they only left one plug unchanged, they sometimes forget to put back the intercooler
What a bunch of crooks.

 

Any idea who makes a 1/4" drive spark plug socket?

 

Phelix you have to reduce down from 3/8 to 1/4 with a adapter..
