Yes it did. I got a 1” shroud from wizard with 4 staggered spall fans( they just cleared the moroso electric water pump) . Engine temp was 175 highway, never went over 190 sitting in traffic when fans started up. Wizard told me a shroud should be no shorter than 3/4” deep coz it makes a high pressure in front of the rad which in turn forces the air faster through the openings by the fans. It worked for me.
