Hey mate, just a quick point to look out for when getting one of the cheaper mass produced coolers, see if you can get a look at the fins inside the cooler before buying, as I was looking into getting one of these before and found that some of the bar and plate type ones have a pretty poor design. They may look good from the outside, but I recon might not have done much to drop charge temps.
Here is pic of one that in my opinion isn't up to scratch, the internal fins simply have holes punched in them.
The fin type below is better, and although this design may give more of a pressure drop across the cooler, it will aggitate the air enough to cool it effectively.
All I am really saying is that not all of the hybrid type coolers are the same, the top pic was a hybrid type one I considered buying on ebay until I got the seller to send me some more detailed pics. I have however seen these type of cooler with internal fins like the bottom pic, and I've seen cars with these on make good power, so make sure and get one of the better ones if that is what you go for.
