Dynadog, I do not use the fancy spark plug tools. I use a small Snap-on pry bar to pop the wire caps off and then I use a Craftsman deep drive socket to remove the plugs. The Craftsman socket is smaller in outer diameter than any of my other deep drive Sockets. I have Snap-on, MAC, and S-K but only the Craftsman was small enough without turning down the outside. As to oil filter wrench, I tried one after market that was a POS! so I bought one from my dealer. $35 US but it works with no slippage!
