Old man,I take that as a compliment .and yes I have heard of a heat sheld and have not seen one that will work as well as a fully sealed system . I have also heard of a dyno and a thermomiter and have tested (on my 2005 Chevy 2500 hd with a Dmax ) and no shield available worked as well as the stock air box from a 2006 that I retrofited to my 2005. It must be nice to be young and know everything .and by the way this 56 year old man can say with pride that not a day goes by that I cant learn something new . just for fun light a cig and put it iside of your choice of shields and see if you dont see smoke escape . and by the way Carol Shelby is an old man too ,mayby you know more than him too .
