Hey Tony, I did a bunch of cooling system mods but green is for sure the fastest color. The BPD diesel water pump is a thing of beauty but these rigs are not really known for water pump failures. That said, I did discover one of the plastic blades broken when I replaced mine at 90k. Plastic radiators don't make much sense to me but wow the aluminum Performance option has doubled in price since I bought mine. https://shop.performanceradiator.com...roduct_id=5296 https://www.dieselsite.com/2003-2007...waterpump.aspx
Hood louvers don't really do much when running but I do think they are of benefit when stopped, allowing the heat to escape the cramped engine bay and hopefully lessening the time the wiring harness and plastic connectors are getting cooked. Who knows but they look cool! E350 Sportsmobile - Hood Louvers | RunCool | Hood Vents For Your Vehicle -

Agreed! I have the medium size ones on my 2002 E350. Not much difference driving, but I do notice a difference in stop and go in the summer heat.
Color wise, I'm in the same confused state of green vs sand/tan. I'll probably go with sand/tan on the off chance it'll make the van cooler.
