These are only OK

These will work OK, but they came just stampled plain aluminum, and not Anodized as shown. I would think the anodized versions better to resist corosion but these will work, could have just made my own knowing not anodized.

I believe I have the 3/4 inch one in now...and I want the motor to run a little cooler. It's in a street stock dirt car turning 6500 rpm. Would I go larger or smaller??
