Yes, replace them. The wear looks normal for the time.That gap looks a bit large. Keep the gap within specs. Set at minimum and readjust when they hit max gap. A gap out of max will strain the coils and cause coil failure.
I am at 260 hrs and just did my plugs, exactly like that. For $2.50 each I will just replace every 200 hours or so. Wish the mag plugs where that cheap.

Get the solid cap plugs not the screw on cap. If I remember correctly they have a different number on the box for each or they just say solid cap or screw on cap they come both ways. I use the BR8ES and change them every year, they are cheap or should I say inexpensive.
