Foam strip under the radiator

Hi everyone,
When I removed my original radiator there was a foam piece glued along the bottom of the radiator and up the sides for a bit.
I want to replace it to direct the airflow through the radiator to help cool the engine.

Does anyone know of a suitable replacement that will last for a long time?

The original foam was 34mm wide x 34mm tall and the length was about .870 mm long.

Any ideas will be appreciated, thanks!

I went to my local surplus center and found a big square of foam, cut it to width, and used weatherstrip glue to hold it on. Works well!

A roll of thick foam insulation from Home Depot of Lowes that helps seal gaps around windows and doors. The one I used had it's own adhesive, i just applied it to the bottom of my aluminum radiator. You can double it up (stack it) for better seal.

i went to the hardware store too, they had a whole bin of different foams, and i found one the same-ish size.
the foams you'd buy here aren't metric, so the cells in the foam are the wrong size, but if you can get over that it works

Thanks for the information, I will buy some and stack it up to fill the space.

This foam piece is for windows, I hope it holds up for a decade or so!
