Which plugs are you lt1 owners using.I was going to use ac delco but have been told that the platinum pucks delaminate, causing premature fouling.I have been told, ngk55ir are a better choice.thoughts.
 
I haven't seen mine yet but I believe they are OEM (Delco).

I believe Manny suggests either NGK or OEM's. A quick pm will get your answer.

Have lots of u-joints and extensions handy for the job. A few of them are a real PITA to get to.
