I have read an article somewhere - cannot remember if it was magazine or online but they researched temps vs colour and there was not much in it black or silver. If I remember I will reference it
The original white van allegedly came from the ford transit chaps leaning against a dark van and finding it considerably warmer than the white ones - cannot remember the specific temp difference but it was enough to create the white van man legend
so whilst stationary yes you will have increased temp vs a white car but once moving the intercooler difference will be little. Misimoto are banging out some quality gear at the moment so as a brand I would but their stuff - I have the OAS marked as must have for our next hatch.
Only other thing that may be of consequence is that I have read somewhere - again apologies as I cannot recall where, that the intake for the sharkeye is ineffective at higher speeds, so further investigation may be required there...??
