I just bought one of these for $225 shipped which is a really good price. Volant is one of the higher end intake companies. They have a great rep with the corvette guys.
It looks like this box will prevent water intrusion far better than the other intakes I've seen.
I have no affiliation with the company. I just thought I'd pass along a good deal.
