id say keep it stock but definitely add the air panel and maybe some silicone hoses. as long as you keep up with your coolant you should be good. theres also collant additives you can add for your trip, such as "super coolant".
if you really wana be balzy about it, cough up the extra dough and go Mishimoto on the cooling setup. a little pricey at first but definitely goes a long way with their LIFETIME warranty
