Champion radiators and fan shroud

[Nero]

Hey all, so I'm finally gonna look into this....
After swapping out my brass rad for a 3core aluminum one, I have almost an inch of space between my fan shroud and the radiator. I'm pretty sure thats affecting the air flow efficiency, so wanted to ask, for those who have swapped to a champion aluminum radiator, what did you do to fill the gap effectively?

I have a champion. Went out and checked, the gap is on the top and the bottom, and on mine it's only like 1/2 inch. I never noticed it before, but have been running for years like that with no problems. A piece of some sort of rubber or stiff foam mounted to the shroud should take care of it.

+1 on the same question - i have the same issue on a Mishimoto 3 row.

If all else fails, maybe some pipe insulation might help. At least that's widely available and pretty inexpensive.

I went with the pipe insulation route on my 4 row Champion radiator.

It wouldn't matter to me since I couldn't see it while I was driving.
