The COBB Tuning Heat Shield was developed to capture the cool air supplied to the SF Intake through the factory intake snorkel. Constructed of 16 ga. Aluminum, the heat shield consists of a one piece surround, directional lid, and stainless fasteners that help reduce a loss of power that could be robbed from your motor by a heated intake charge.

cobb intake box
maltonafamily48626 3 months ago
Installed this on my 2010 WRX. I also installed reflect-a-gold tape on it as well. Fitment was pretty good. Prior to installing i noticed roughly a 30 deg difference from intake temp to outside temp while cruising. Now with the box installed and cruising down the highway, it is a less than 10 deg difference. Highly recommend this product.

Took about 30 minutes to install and sounds like a BOV... not sure if I noticed a little seat in the pants go from this or the accessport

OK Air Box

Overpriced for what you get, an aluminum shield (Not really a full box). The opening for the COB intake is too big, doesn't keep out enough hot air. The box gets hot to the touch

Function) I purchased this in the stage 1 bundle for 2013 sti so I cannot offer my observations of the (before vs. after) intake temperatures. Over the last few months it seems my intake temps hover approximately 8-16* above the ambient air temperature while cruising (40-65 mph) and while stopped at longer traffic lights or idling for a few minutes climbs up to 20-35* above the ambient air. I wouldn't want to test without the box as I firmly believe it would only give me hotter temps anyway. In hindsight, I would like to wrap the outside in the gold heat wrap, but because of the install, I'd rather not pull it back out. This leads me to the form. Form) The box is beautiful, smooth, and fairly sturdy. Unfortunately, the engine bay was pretty tight when installing this, so I had to maneuver the box quite a bit. And I had a hell of a time getting the bottom of the air box to line up with the bottom of the intake support bracket. It also took some man-handling to get the lid onto the top of the box. I do appreciate that this set up utilizes the factory air snorkel up front. ETC) The package came with all the hardware needed, instructions were not provided, but there is a video for it on here if you need it. Overall I am satisfied with the purchase and would recommend it. As usual, Thank you to RSD for fast accurate shipping and great service.


  • AnswerQ: compatibility?  kndrii 9 months ago

    Is it compatible with the K&N Typhoon Short Ram Intake?

    • A: We can only confirm fitment with Cobb's SF Intakes.

  • AnswerQ: Power Difference  JerryR 1 year ago

    How much of a power difference is there with using the intake airbox and not having it at all?

    • A: We do not have an exact number on how much extra power the airbox creates however, it does significantly lower your intake temps which will make your motor happy as well as add a little power.

  • AnswerQ: Cali weather  JerryR 1 year ago

    If I live in Los Angeles...would I really need this since temperatures rarely are too hot or too cold? I ask this because I also want to add an FMIC but the Cobb intake wouldnt fit unless you delete the airbox off of it.

    • A: The airbox will aid in cooler intake temperatures, which means more power. But it wouldn't be necessary to run the intake.

  • AnswerQ: Factory Air Scoop  WDB-2 2 years ago

    Does the factory air scoop attach to the box to help provide cool air or are the pictures I see on here just for looks? I cannot tell if there is a cut out of the Cobb box to allow the air to actually enter.

    • A: The factory air duct attaches to the airbox and will provide airflow into the airbox.

  • AnswerQ: Airbox w/ Stock Inlet  mferrell590 2 years ago

    Does the box work the same without the stock air inlet or does it require that part to work properly?

    • A: The Cobb Airbox will work with either the stock or Cobb post maf hoses.
