The two big bolts that hold the air filter body and sort of the throttle bodies etc. on the front of the engine have started to discolour / corrode and I think there are one or two others that seem to lose their newness rather quickly. Car is only 4 months old so not exactly ideal and I will also ask my dealer...
Does anyone have any recommendations - should I just paint, or can these be replaced with stainless bolts or whatever?
