My Reatta was still rocking it's OE plugs and wires when I picked it up, making replacement high on the list of initial "to-do's".
The OE R44LTS6 plugs were barely snug, and gapped at around .080". The wires were very crispy, definitely showing their age. I replaced with a set of ACD 626D wires and NGK TR55 plugs.
Initial thoughts: starts much faster and smoother, and the misfire when the TCC is locked and load is applied is gone. There really is something to be said RE: how smooth a properly running 3800 engine is.
