    Great Intake! 3 years ago

    High quality intake and it fits great! I included a highly detailed video of the install if anyone was unsure how to install it.

    Sounds much better under the hood. I have the stock BOV and you can hear it much better now. The car feels a bit better under boost as well. Install was simple and fast with basic hand tools. Cleans up the appearance of the engine bay as well because it deletes a lot of plastic. The wrinkle red finish is not quite an exact match but so close that you cant tell unless its pointed out in a well lit area. (and I'm super picky here) Very good product and fast shipping. Thanks Rallysportdirect!

      What do we do about the tube running from the factory intake tube to the firewall?

        A:  The factory sound tube going to the cabin will not be connected to this intake and you can just leave it disconnected or remove it from the car.
