Below are 3 links to 3 different radiators I've found after sorting through rx8club's couple dozen radiator threads. These seem to have come out ahead, except the megan radiator, which I didn't see anything definitive about. Leaning towards Koyo based on all the +1's about it. What about the other two?

Additionally, I am ordering some hoses for the radiator, as well. Found a set by Agency Power, but only the 2 that come out of the radiator itself. I can't find any for the radiator reservoir hoses that wrap around the battery. I know Mazmart has what I'm talking about in black. Do you know where I can find the same stuff in red? Will order from them if I can't find anything else.


Lastly, Battery tray, cover, entire thing, etc. Because it holds hoses in place, and the battery for that matter, are there any upgradable options? Mine is cracked and I'm looking to replace. Will go OEM if no other option, but was just curious.

 

I think I may have just found my 6 piece hose set.

However, it says it is only for 2007-09. Would that fit an 06? What are the differences?
