    No, it doesn't. Not by design. It's for heat only.

    It is not recommended to confirm proper installation by driving into walls or other barriers as this could cause personal injury or damage to the vehicle.

    Sure looks like it does to me and others agree. You didn't engineer and/or design it and I don't think you've done any wind tunnel testing on it either. Nor have you quoted or shown any evidence to support your opinion but you stated it such as being factual. Not trying to start anything.

    Who do you honestly think is a better engineer? You or Nissan Motor Company?
    Good for you replacing your master cylinder, though it is irrelevant to the question asked.

    It was irrelevant because your heatsheild was STILL IN PLACE. It could have failed for many reasons. Most likely because of age.

    I guess then, by popular opinion--since it looks like it does, then it does.







    This directs air:

    It sits directly at the back of the hole in the hood for the scoop. Haven't looked at it in a while but that looks different iirc. I'm going to dig it out of storage when I go to get parts out after work.

    The point I tried to make is that it's not sealing anything. Saying it "directs air to the turbo" is like saying that your hand "directs water to your mouth" when your fingers are spread apart.

    Got ya, but you can't deny removing it will affect where the air entering the engine compartment from the scoop opening goes.

    I take it nobody has any melted plastic reservoir tanks or melted wires because of removing it then? Looks like it is alright to leave off then. Thanks.

    Mines off since I did the turbo swap, I plan to put it back on this weekend though.

    Took mine off. The downpipe off the top mount turbo is wrapped and doesn't get too hot.
