Spark plug replacement 2008 G.C.
I looked thru the entire owners manual for my wife's 2008 G.C. and can't find a recommended mileage for replacing the spark plugs.
Anybody know?

You should be able to find it in the owners manual in the Maintenance Schedules section. It says to replace the spark plugs and wires on the 3.3L, 3.8L and 4.0L engines at 102,000 miles or 102 months, whichever occurs first.
