Are you sure about that? What did it weigh and how much did the non-OE alternatives weigh?

Thank you for picking up what I was putting down, Savington. Nagase - my point was that you can't say whether or not the Koyo 37mm is or is not the lightest of the common upgrades.

What do you do with the car? Is this for the normally aspirated NB? Why do you need something other than the stock? Are you currently having cooling issues?

I wonder which is more important, weight saving of 6-7 lb on the radiator or the higher heat exchange to prevent overheat on other than normal conditions/engines?

Overheats are bad, then? Tell us more. :fawk::noob:

Overcame the thermal capacity of the stock unit while driving... playfully.

Ordered up the TSE anyway.
