This sounds reasonable. What does the manual say?? My 2012 Honda fit maintenance minder came up at 120k for plugs, valve adjustment. My factory plugs looked almost new and the valves were all inspec.A 4-cylinder Camry is very easy to change them on. It came with Denso or NGK iridium from the factory, or sometimes even both. When you remove the old ones, you might actually find 2 Denso and 2 NGK plugs, and they will look almost new.
Replace them with Denso Iridium TT, or the original Denso or NGK iridium.
I think the interval is 120k
