PhilD,
You have to remember that these are some of the same dealers who install inferior aftermarket sunroofs in H2's because they just didn't order them with the factory sunroofs. Instead of ordering a $500 3rd row seat for every vehicle, why not order every H2 with a sunroof. The dealer could then weld a steel plate over it if someone didn't want the sunroof...
If the dealer can make a few extra bucks by adding the non-stock air intake, it's just more money in his pocket...
But you are right. It does seem awfully DUMB.
