Also consider the vehicle when reading anecdotal evidence pertaining to open air element filters on forums. A Corvette or Camaro doing in town driving will have much higher under hood temps than a 4x4 pickup with a large grill and no inner fender skirts circulating air around an engine bay that could fit 3 small blocks on a 55mph commute with 2 stop signs. There are many variables to each combo. I am looking around for a cold air intake, but I’ve read about certain downsides on that side, too. I may get a oem type dual snorkel here, but I’m not expecting miracles.
