Read the page at the link I posted above.
1. Your intercooled intake charge temp is close to ambient temp
2. An intercooled charge with WI (which looks like is going to be very popular) should be at or below ambient temp
3. The stockers are lighter
4. The stockers are cheaper
5. The stockers work
6. The stockers will not have any fitment issues
7. The stockers are known to last 10-15 or more years
I would _theorize_ (meaning I haven't put any effort into validating) that a stock radiator with some sort of undercar airfoil (to direct airflow in) and a plate over the radiator cowl (to prevent escape) would well outperform a typical metal aftermarket radiator--and would cost and weigh less too.
I'm running my 15 year old stock rad with a small airfoil. I have no temp issues in Atlanta rush hour (some of the worst traffic in the country) in the summer with a/c on. I live near Road Atlanta. No temp problems there, either.
