Ahem...

I don't know either why Hayden chose a copper interior with an aluminium exterior. It might be a cost issue (given the price of copper), but the added manufacturing step surely nullifies the savings. Maybe it's more of a functionality thing: copper will oxidize rather rapidly, especially left outside, which may impede performance. An aluminium exterior would be ideal for a car.

The Hayden tranny cooler still runs at more than 60$US, and it's hard to justify that cost, unless there's a need for a small but efficient radiator. Still airflow is critical, and that doesn't change with the size of the rad.

I'll have to go to my local auto shop sometime, and open up a box to see. What I don't like is that from the exterior, it looks "all aluminium", which would mean that the inlet/outlet would have to have this aluminium scraped off. Hopefully the alu doesn't extend a bit inside the tubes, because that would be a pita to remove.

Anybody got their hands on one of those famous Serck coolers? I almost bought one off eBay the other day, but didn't care to spend the money for shipping from the UK.
