Nope not a waste of money,but build your own!
I revised all of mine and replaced the grille with alumininium (or should that be aloominum )mesh fitted 100mm pick ups directly beside the radiator fix to the bottom of the shroud and heat resistant tubing to stock engine intakes.

Drags cold air in well, Add K & N 's rework the internals of your stock engine cover to increase flow and voila a few hours work colder air, better flow and more HP.

BUT remember I am not particularily interested in apperance just power.
Just nmy two bits total cost excluding the filters around A$100
