i've checked my turbo temps after just cruising around and they were around 600 degrees, obviously cooler further away. I have no snorkus in the fender and most of the air is coming in from the fender hole or in front, so I believe it is functional.
obviously going to a cai would be better than sri, but for now this is what ive fabbed up.
Keep in mind that the idea of a heat shield is to prevent radiant heat from entering the engine bay (i.e. why there is one over the turbo). Putting a piece of metal around the filter of a hot air intake if anything will just provide a hot surface for colder air, provided it is entering through the fender, to run across and heat up pre-intake.
You would probably be better off facing it towards the turbo instead of the hood to boot, but I'm guessing its just for looks. Probably can't hurt much more than having an open filter in the engine bay anyway
