Hi K, Thanks.
Honestly, I don't want to do any modifications from OE config other than bolt-ons. So, I don't want to cut them off. The down side...they will be visible through the grill. The car did have electric fans when I got it which I will reuse (or replace if deemed necessary after closer inspection). What do you mean by air plenum though? Is there some sort of plenum that it is suggested that I fabricate?
