Product Description
This WRX top-mount intercooler utilizes durable cast aluminium end tanks TIG-welded to a highly efficient and dense bar-and-plate core. The Mishimoto WRX intercooler has a 3.75 core and a total volume of 584 cubic inches. Thanks to this volume and a very dense offset fin pitch, we are able to optimize heat transfer and support vehicles from stock up to 400 whp. This WRX intercooler endured rigorous testing, showing a 12°F temperature drop as well as a +6 whp and +8 wtq bolt-on power increase for our stock test vehicle. Installation is simple, requires no modification to any parts in the engine bay, and can be completed in under 30 minutes.
This top-mount intercooler comes with a new turbo-intercooler O-ring gasket, and Mishimoto's silicone throttle body coupler. These WRX parts negate the need to gather supplies for installation, and they ensure years of reliable service. This WRX top-mount intercooler is available in a durable powder-coated finish of Sleek Silver or Stealth Black, and it includes the Mishimoto Lifetime Warranty.

Testing time! Well " almost. We had a few quick testing details to sort out and some preparations before we actually began. First, we needed to drill and tap the stock intercooler as well as the Mishimoto prototypes so we could install our pressure/temperature sensors. Additionally, we decided to create a shroud for our TMIC fan to ensure that all cores would receive appropriate airflow on the dynamometer.
Tapping the intercoolers for sensors is a relatively straightforward process. We drilled into both end tanks and then tapped them

Last time, we left you with a teaser of the rendering for our prototype of the top-mount intercooler (TMIC). Since then Dan has been hard at work refining his design. Our team worked up some CFD analyses of both the stock intercooler and the Mishimoto prototype. And, we also worked up a few functioning prototypes so we could begin real-world product testing. This project is moving quickly and our team is rather excited to see the outcome. Take a look at the finalized rendering of our cooler below!

Nothing sets off a Subaru engine bay like a nice beefy top-mount intercooler. Not only does a big TMIC look great, but it is also instrumental for keeping AITs low and your EJ happy. For those seeking low AITs on a stock to mild build, an efficient top-mount setup is the way to go to avoid inheriting the pressure drop and lag from a front-mount intercooler. Not only this, but the TMIC prevents any road (or off-road) debris from damaging your heat exchanger. This is key for those who are involved in any rally, off-road, or rallycross events.
If you keep up with any of our social media outlets, you are likely aware that Mishimoto has been working to develop a TMIC for the 2008-2014 WRX. We are very active within the Subaru enthusiast community,
