(S7 with aluminum radiator, if it matters)
The manual states to trim the aft edges of the duct to have "a constant gap" between the duct and the face of the radiator.
My question is, How close is close enough? Are most folks trying to minimize the gap (or even use a seal to fill it) to force air thru the radiator or going pretty generous on the gap.
My thought was to go for a 1/4" gap to the end pieces (would be 3/8" or so more to the actual face), but would like to hear from others as to your setup and results.
