Ask a Question

The ETS 2015 Subaru STI Front Mount Intercooler Kit is a high-performance intercooler system designed specifically for the 2015-2019 Subaru WRX STI models. 

The intercooler kit is designed to significantly improve the cooling efficiency of the intake air, resulting in increased horsepower and torque gains. It effectively reduces the temperature of the compressed air from the turbocharger before it enters the engine, ensuring a denser and more oxygen-rich intake charge.

The ETS Front Mount Intercooler is constructed using high-quality materials to ensure durability and optimal performance. It features a large core with a high-density bar and plate design, allowing for maximum heat dissipation and efficient cooling. The intercooler core is made from lightweight aluminum, which helps to minimize weight while maintaining excellent strength and cooling capabilities.

The kit includes all the necessary components for a complete installation, including stainless steel piping, silicone couplers, stainless steel T-bolt clamps, and an optional high-flow blow-off valve. The stainless steel piping is mandrel-bent for smooth airflow and minimal pressure drop, ensuring optimum performance. The silicone couplers provide a secure and leak-free connection between the intercooler and the turbocharger and throttle body.

Installation of the ETS Front Mount Intercooler Kit is straightforward and can be completed with basic hand tools. 

With the ETS 2015 Subaru STI Front Mount Intercooler Kit installed, drivers can expect to experience improved throttle response, increased power throughout the entire RPM range, and reduced heat soak during spirited driving or high-performance applications. Whether you're a weekend warrior or a track enthusiast, this intercooler kit provides a significant upgrade to the cooling efficiency of your Subaru WRX STI, resulting in enhanced performance and reliability.

In addition to its exceptional performance, the ETS Front Mount Intercooler Kit offers a range of options to suit your specific needs and preferences. You can choose from multiple intercooler thickness options, including 3.0", 3.5", 4.0", and 5.0", to match your desired level of cooling efficiency. Furthermore, you have the option to add an ETS logo on the front of the intercooler for a personalized touch.  This feature allows you to proudly display the ETS brand while enhancing the visual appeal.

The intercooler kit is compatible with various turbocharger setups, including the stock turbocharger, aftermarket bolt-on turbochargers, and ETS's rotated turbo kit, providing flexibility for different performance goals. It is designed to fit both the stock intake manifold and the Process West intake manifold, ensuring compatibility with different intake setups.

To further customize your intercooler, ETS offers a variety of anodized finishes, including blue, red, black, gold, and purple, in addition to the standard silver finish. This allows you to select a color that suits your personal style or complements your vehicle's aesthetic.

Please note that the installation of the intercooler kit requires the removal of the factory bumper beam. As an optional accessory, ETS provides a chassis brace with a tow hook, offering additional structural support and a convenient towing solution.

Overall, the ETS 2015 Subaru STI Front Mount Intercooler Kit combines exceptional performance, durability, and customization options to enhance the cooling efficiency and power output of your Subaru WRX STI.

Note: We now include an AIT Bung w/ Plug by default.  No Sensor included.

Ets FMIC a must have!

Ask a Question
  • I saw that this wont work with the Cobb SF Intake but will it work with the Cobb Redline Intake?

    This will not work with the Cobb Redline Intake - the airbox occupies the space needed for the piping.

    The ETS Sales Team

  • do you ship to alaska?

    Yup!  Please drop an email to sales@extremeturbosystems.com with the sku you are interested in and we can calculate shipping if the website is not calcualting correctly.

  • does this work with a cobb sf intake with airbox? or will the air box need to be altered

    This will not fit with the Cobb Airbox without modification

  • I see different color ETS logos painted on the core, how would one go about getting a specific color logo with anodizing?

    When placing the order, you can add the stencil color to the order notes if you have a special request. We cannot do exact color matching, but we do have several different options. Additionally, if there is a specific paint/color code you can include that as well.

  • I bought a used ets front mount locally and it came with a tial bov. I already got the car tuned with the tial bov. If I was to switch to the hks would I need a retune?

    If your vehicle is tuned to speed density you shouldn't need a retune, but it's always best to ask your tuner.

  • Will this work with a process west intake manifold?

    Yes, but you will need to order our piping kit and intercooler through the following links.



  • Sorry to bother you..... If I do a front mount and piping kit, do I need to get my car tuned..? I'm looking to do this kit more for a visual look (I know, I'm weak sauce). I'm driving a 2021 Subaru STi with only a cat back and drop in filter. Thanks for any answers you can provide, I truly appreciate it.

    No problem!  You don't need a tune to run a front mount intercooler.  We do reocmmend that you recirculate the blow off valve like factory to prevent any type of driveability errors.

  • I see the only manifold option is stock. I plan on using an AMS manifold. Will there be any fitment issues?

    Our intercooler kit will not fit an AMS intake manifold without modification.

  • May I install this kit, can I continue to use AEM's air intake system?

    Doing a quick google search it looks like the intake shield will not work as it would block our piping from running through the fender.  The pipe looks close, but with never installing an AEM intake I can't say for sure.  Worst case, we offer an intake that is PNP with our intercooler kit.

  • Is a Cobb 20g turbo considered a stock turbo replacement?

    Yup!  The Cobb 20G utilizes a 2.0" compressor cover, so you will need our stock replacement turbo piping kit.

  • If we want to get the HKS SSQV4 BOV with the kit, will it be compatible with the Tial BOV flange? That seems to be the only flange option..

    There should be an option to select TiAL, HKS, TurboSmart or PTE.  The flanges are different between the different blow off valve models.  If you can't find what you're looking for send an email to sales@extremeturbosystems.com and we can help you out.

  • I have the Cobb LF BPV, would i select stock BOV flange? Thanks!

    Yup!  Select the stock flange to run this blow off valve.

  • Do you guys have the ait bung already welded on cause I don’t see the option for it any more on the list of configurations .

    Yep, it comes welded on and we include a plug in case you don't need it.

  • If I were to buy this kit, is the IAT bung welded on already or do you have to ask for that? Considering Titanium piping

    It comes included with a plug. No need to specify.

  • What is the cuppler size for the stock turbo replacement ?

    Stock Replacement is a 2.00" to 2.50" 90 degree coupler.  The factory turbocharger size is a 1.75" to 2.50" 90 degree coupler.



  • If I get the stock turbo location pipe setup and decide to replace the turbo with an upgraded stock location turbo, is there a way to replace just that pipe?

    The pipe is the same. It is just a coupler change.

  • Hi so I was about to order your front Mount kit but I’m not sure if I need to pick 1.75 or 2 for the turbo. I have a bloush 20g and am just curious what size I would need thank you.

    The measurement is for the compressor outlet on your physical turbocharger, the only way to verify 100% would be to measure your existing compressor outlet. 

    Generally, most OEM Subaru Compressor outlets will be 1.75", and most aftermarket stock location upgrades will be 2.00", but you'll always want to measure for your own specific application if you are unsure.

  • Can I get the piping in wrinkle red if specified?

    We only have the ability to coat in wrinkle black, but we can leave the piping bare by request if you'd like to have a custom powdercoat applied on your end. 

    Just include that information in the 'Special Instructions For Seller' section and we'll take care of it for you!

  • Does the Blouch Dominator 1.5 XTR use a 2" coupler?

    Yup!  The Blouch Dominator has a 2.00" outlet.

  • Would i be able to run the tial qr (recirculating version of the tial q) and still recirculate it with tial flange on this intercooler?

    If you would prefer to recirculate the valve, this would be a viable option as they use the same 50mm flange. You'll just need to ensure that you purchase the correct size outlet for the BOV. Our recirculation hose is 29mm ID (1.14") for reference.
