I don't know if it's picture shadows or what, but those vents look like they will not allow much air flow due to the small overall hole size, especially the passenger side vent. Don't think they will do much good for you unless you can open them up with a Dremel or something. The reason I say this is because I tried some 98 ZJ hood vents w. bigger flow holes, and they really didn't help much, especially at crawling slow speeds in hot weather. Went to the cowl hood and that really did all I expected of it.
