Just do what the drag guys do and drop a load of ice into it

While I like this kit, I prefer air-to-air intercoolers on the street simply because there's less to go wrong. AWICs can cool very well, I've just always been wary of that scenario where I need to fill some water and I don't have any, thus stranding me.
Though trying to get a blown coupler reaffixed onto an air-to-air IC charge pipe on the side of the highway is no better AND I've actually been in that situation.
