Foam between the radiator and condenser

[Huskymaniac]

After doing some reading, it became apparent that this foam is not just a minor afterthought of the original engineers. The foam serves its strongest function while idling or driving slowly. Without it, the fans will suck in hot engine cabin air through the gap and then through the radiator. It can make a big difference in operating temperature. At speed the effect is less but the foam does stop cold air from bypassing the radiator after it has been brought in through the grill and condenser. It probably has a minor impact on operating temperature.

I am considering this for replacing my old deteriorating foam:

I was thinking of part number 8865K52 and then cutting out strips from the sheet. It is high temperature foam with a high temperature adhesive.
