Direct fit for the 2015-2021 Subaru WRX
Will not fit right-hand drive (RHD) models unless the washer fluid bottle is removed or relocated
3.5" Thick intercooler design optimized for maximum flow
Here at Mishimoto, we've decided to expand our line of 2015-2021 WRX parts. Designed for applications that demand the greatest airflow and cooling capabilities, the Mishimoto 2015-2021 WRX Front-Mount Intercooler Kit provides your 2015-2021 WRX with the ability to make the most horsepower and torque possible. This 2015-2021 WRX intercooler was designed with a large 28 intercooler core that provides the maximum cooling capability without excessive pressure drops that wear out any turbocharger over time. The Mishimoto 2015-2021 WRX front-mount intercooler features smooth cast end tanks that are CFD tested for maximum airflow with no sharp walls or bends from cut-and-weld end tanks that disrupt airflow. The intercooler provides the best airflow and heat-exchange properties for those time-attack laps, or a 10-second blast down the quarter-mile.
The Mishimoto Subaru WRX Front-Mount Intercooler also features four mandrel-bent aluminium pipes for optimum airflow. The hot-side pipes are 5.7 cm in diameter to keep airflow velocities high, giving your car an instant response without the excessive throttle lag that plagues many front-mount intercooler designs. The hot-side pipe also features a CNC-machined flange for a leak-free connection to the turbo. The cold side of the system features 6.35 cm to 6.9 cm mandrel-bent aluminium tubing for maximum airflow and to match the diameter of your throttle body.
This 2015-2021 WRX front-mount intercooler kit contains everything needed for a worry-free installation, including an application-specific crash bar that both supports the intercooler and mounts to existing points on the vehicle. No cutting of the front bumper or drilling is required to install the crash bar and intercooler. The kit includes all necessary mounting brackets, including a new bracket for the air intake. Our 2015-2021 WRX front-mount intercooler kit also includes every coupler and clamp you need for a clean install, and complements the Mishimoto Subaru WRX Performance Air Intake for added cooling power.
Mishimoto tested this WRX intercooler on our Stage 2 265 whp 2015-2021 WRX to find significant drops in AITs (air intake temperatures), and it has also been flow tested to over 600 whp! The 2015-2021 WRX front-mount intercooler kit is available with either a Sleek Silver or Stealth Black cooler and, like all our 2015-2021 WRX parts, includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
This kit does not fit with fog light equipped vehicles
Mishimoto recommends that this intercooler kit, not be used with the stock ECU programming. It is highly recommended that the customer be able to retune the vehicle's ECU after installing the intercooler kit. Power gains will vary depending on the size of the turbo, exhaust system, fuel system, and type of ECU tune that is applied to the vehicle.
This kit is rated for approximately 600 whp during normal operating conditions. Maximum horsepower potential will be near 700 whp. Exceeding these horsepower or pressure limits could require a custom-size front-mount intercooler.
This front-mount intercooler kit will not fit with the Mishimoto 2015+ WRX oil cooler kit
This front-mount intercooler kit will not fit with the Mishimoto 2015+ WRX oil cooler kitThis kit is not compatible with some air-oil separator kits.

Time for the fun part of development, product testing! Since this is an intercooler, we would certainly need to put the WRX on the dyno for some pulls and data collection. It would be interesting to see how the installation of a front-mount system has an impact on turbo spool, intake temperatures, and perhaps even power output.
Testing Preparation
The first step toward data collection is to prepare our sensor bungs and install our pressure and temperature sensors. We installed our bungs within the inlet and outlet intercooler couplers.
In the last portion of this series we completed the fabrication of our prototype intercooler core and tanks, as well as our new bumper beam. We now had everything in place to construct a piping kit that would route air from the turbocharger to the intercooler and back to the engine.
Hot-Side Piping
We started our piping with the hot-side of the intercooler system. The stock compressor
After an unsuccessful test fit of our existing bumper beam on the 15', we started from scratch to create a beam specific for the 15' chassis. First we hacked off the end tanks of our cooler so we were left with a bare core. This would provide some freedom to design our crash beam and later work on the end tank direction. Next we cut out some new mounting plates and fit them into position.
Already outgrowing the efficiency of your 15' WRX top-mount intercooler setup? Planning for some big power in the near future? Sounds like your Subie needs an efficient front-mount intercooler (FMIC)! Luckily, our team has been working to develop this product for months. Check out the process below!
