yes you can jet hot your intake. jet hot can do the top and bottom or just the top, whatever you're willing to pay for. here is a picture of the bottom of mine that shows what jet hot calls a thermal barrier coating, sorry I don't have a pic of the top but it'll look pretty much like the header coating.
