Any other opinions/. How much better does an aluminum radiator work than a stock 3 core does?

Wow...that does seem backward, heating up on the highway like that! Strange. Not exactly sure what you meant by "how much better"...but a larger, aluminum radiator works MUCH better than the thin stock unit. It helps everything run cooler. I saw a difference on my temp. guage for sure.
