Description

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 gauge 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. 

This heat shield has been powder-coated a nice black finish to blend in well with the engine bay and to provide extra protection and support against rust and corrosion. Hardware, a tool for the hardware, as well as a seal will be included to make this heat shield ready for installation.

himvictor 1 year ago
If your ever planning to get an intake system for your subaru impreza wrx sti i highly recommend the COBB tuning SF Intake with the air box. Install was okay not too hard. very clean intake system set up. if your the type that love to make your engine bay look clean and also get very good performance this intake is for you. you can hear the turbo spool up with this intake. make sure you get your car tuned afterwards!

Decent, but seriously disappointed.
Synapse 1 year ago
So for this kind of money, you would think that you're going to get a solid product. Which you do, sort of. For this kind of money, you would think that you're going to get something you can't make yourself in your garage. And you do... Maybe. You would also think that, being designed as a direct complement to the Cobb SF Intake, this product would mesh and interface with that product perfectly, that it would do its advertised job and act as a heat shield from the rest of the engine bay, and that it wouldn't make you worry about any necessary stock equipment that you must bolt up to... well, you'd be wrong. So, when you install this, the first thing you'll notice is that the metal feels like it's of decent quality, and the finish is good. The next thing you'll notice is that it doesn't come with any instructions. If you're a real man, though, you don't need no instructions. Fiddling it into place and figuring out how to get the whole kit together probably took about 20-30 min, but it all sort of makes sense once it's put together. Pros: + Allows you to keep the stock air ram (it plugs into the rectangular cutout on the airbox). This allows you to get cold air from outside the vehicle, without having to worry about running over deep puddles like some who put their intakes in the wheel well. I also think this is the coldest possible source of air for this car, as the wheel well may swirl some heat around from the engine bay, possibly take a little off of the brakes, and in general I'd worry about the elements, especially in the winter. + Decent quality materials (exception of the supplied plastic washers--you can't give me 4 rubber grommets with this overpriced piece of sheet...metal?) + Included rubber weatherstripping material is a nice touch, but there was only about 1/2 the amount I would like to have seen/used. + Looks good in the engine bay. I actually like the "hidden" look better than simply seeing a massive air filter sitting there, like it got lost trying to find some fresh air and then fell in with the wrong crowd. Cons: - Only includes the "cage" and the top plate (and all necessary mounting hardware). There is no bottom plate, so the intake is simply wide open to the wheel well beneath (though you do have the stock plastic wheel well splashguard there to give your expensive filter some protection from the elements). Some may think of this as a good source for cold air, and I might agree, however, for this kind of money, I really expected more than two pieces of sheet...metal and a few screws. Maybe if they didn't give you two stickers with every product they sell... - The SF Intake itself is impossible to fit perfectly in to this cage without having the pigtail for the MAF come into direct contact with the front-most (with respect to the car) edge of the "U" cutout section on the airbox. You *could* correct this by slightly sliding the plastic piece of the SF intake out of the silicone hose, or the SF silicone hose off of your turbo inlet. Since you only have a few millimeters with which to secure both, however, this is absolutely NOT an option and I fail to see how Cobb put out a product that potentially endangers the integrity of something as critical to the car's normal operation as the MAF sensor. You cannot adjust the other way because it would appear that Cobb intended the MAF to fit INSIDE the airbox (would need to move a full 1.5in), but they absolutely FAILED by about 2-4mm. I can't make it work any better without slipping the intake off or potentially damaging the airbox by bending things in ways they probably shouldn't be. - There is no sealing this box. It has more openings into the engine bay than the stock air supply system ever could have. Unless I go and get some sort of insulation and/or weatherstripping to help get a better seal, I am doomed to be sucking hot air from within the engine bay into my intake. The entire point of this airbox is, and I'm quoting the product page here, to "help reduce a loss of power that could be robbed from your motor by a heated intake charge." - This thing gets heat-soaked like you wouldn't believe. Measuring with an infrared thermometer, this is the hottest object in my entire intake tract (turbo and intercooler excluded, of course). Let's put it this way: if it were a steak, it'd be burnt to a crisp (don't recall exact measurements, but heatsoaked on a 90 F day the airbox was in excess of 170 F... and that's NOT COOL. LITERALLY). Again, this REALLY defeats the purpose as the entire idea behind this product, quoting Cobb, is to "help reduce a loss of power that could be robbed from your motor by a heated intake charge." - I have not been able to get ambient/idle vs moving air temperatures yet. It would be interesting to see such results. I may have to run some experiments, but I would be willing to gamble that this airbox actually gives you WORSE / HIGHER intake temperatures than you EVER would have gotten under any condition with the stock intake (at least without taking the corrective measures several people have outlined at this point--see other thoughts). Other Thoughts: - First thing's first, I will be fabricating my own bottom plate for this... series of metal plates that sort of give you a shield from other heat sources in your engine bay, whether it voids my warranty on this product to do so or not. - I will also be investing in some insulating reflective heat tape, and placing that on the inside of the airbox to make sure my intake charge is not picking up any heat off of the metal plates becoming heat-soaked. Understandably, this is likely not so much a problem if the car is actively moving mass amounts of air through the system (much like how your intercooler gets heat-soaked when sitting still, but is usually fairly cool just after a hard run). Regardless, for this sort of money, you'd think they could slap a cheap rubber/plastic liner on one side or the other to at least pretend to combat heat-soak and heat-transfer issues. - I will also be installing insulation/weatherstripping of some kind around the edges of this (and praying that I can find a way to make it NOT look too trashy in the process). So yeah, after buying the SF intake, which desperately needs a tune to work properly (not Cobb's fault), and buying this airbox to make things with the SF intake "better", I can say with great confidence that unless you are prepared to experiment and heavily modify Cobb's "expert" design on your own time, you should probably just save your money for the raw materials and build one of your own. I really should have listened to other reviewers, but I felt like this small investment would save me a great deal of time trying to fabricate my own airbox/insulation system. By the time I work the bugs out of Cobb's design, I likely won't have saved myself much time, and DEFINITELY would have come out ahead on money. Bottom line: if you have the time and know-how, make your own airbox for less than half the price. Only buy this one if you want the Cobb logo (or you could try stickers?), or want to skip the fabrication phase and go straight into the air/water sealing phase of making this product work how it should have after you tightened the last screw down. I hate to be so negative, as this item had great potential. I simply think that like many of Cobb's other products (not to single them out; almost every company has one or two), this one was half-baked and cheaply-made/designed so it could be mass-produced. I should have gone with the Mishimoto equivalent of this intake/airbox combo. It appears to be of much higher quality all around and appears to be of far superior design. And the one that I have seen, for whatever reason, didn't seem to get as heat-soaked as the Cobb. Live and learn.

Must have with SF Intake
PeytHott 2 years ago
I ordered the Air Box after having the SF Intake installed for just over a year. It's a much better idea to buy the combo of the SF Intake and Air Box at the same time as the Air Box installation requires removal of the entire SF Intake system. Installation is pretty straight forward. No directions were provided in the box, so I just watched one of the many install videos on YouTube. Since install I have seen lower temps, so it justified the purchase.

Good product
Mike23 2 years ago
Clean look, pretty easy install if you have any mechanical skills at all. Been installed about three weeks now with some pretty aggressive driving, nothing's come loose yet. Holds up pretty good.

to prevent heat soak the box will help a lot fits with an aftermarket carbon fiber air duct

  • Q: Stock Replacement  DGMboxer 2 years ago

    Answer

    Would this work as a replacement for the OEM air box or would you need to change the intake/filter?


    • A: This does require the use of the COBB SF Intake system.

  • Q: Power Difference  JerryR 4 years ago

    Answer

    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.

  • Q: Cali weather  JerryR 4 years ago

    Answer

    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.

  • Q: Factory Air Scoop  WDB-2 4 years ago

    Answer

    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.
