The one I picked (21x5.5 core) I think was a better choice than getting something like an 18x12 that would go into the top of the bumper away from airflow, this way I have the ENTIRE core exposed to flow.

With my core I will have 115.5 square inches of front face for cooling vs. stock 64 (8x8). With something like an 18x12 which was a common size on ebay, I would have had 216 but I would only have 18x8 eposed, so 144, and with the general largeness of the core I think there would have been more lag.

I'll see when I get it in.
