2008-2014 Subaru WRX

Introducing the Process West Verti-Cooler, a revolutionary slant-mount intercooler system designed for the 2008–2014 Subaru WRX. Developed from years of motorsport engineering and real-world testing, the Verti-Cooler redefines intercooler performance by addressing the biggest limitation of traditional top mount designs—inefficient heat evacuation.

With a focus on rapid charge air cooling and optimized airflow paths, this system delivers unmatched cooling efficiency, improved power consistency, and enhanced engine durability.


Rethinking Factory Intercooler Design

The factory top mount intercooler performs adequately in short bursts but struggles under sustained load due to poor airflow exit paths. Hot air becomes trapped beneath the intercooler, creating a heat-soak “traffic jam” that drastically reduces efficiency.

Simply increasing intercooler size does little to fix this problem.


The Verti-Cooler Advantage

The Verti-Cooler takes a completely new approach by mounting the intercooler at a 15-degree near-vertical angle, dramatically improving airflow dynamics.

This design works in conjunction with a custom hood duct system, which:

  • Forces cool ambient air directly onto the intercooler
  • Allows hot air to exit efficiently downward through the engine bay
  • Reduces heat buildup and restriction
  • Creates a continuous, efficient airflow path

Compared to the factory setup—where air must make a sharp 90° turn and struggles to exit—the Verti-Cooler provides a smooth, low-restriction airflow path for both intake and heat evacuation.


Massive High-Performance Core

The Verti-Cooler features one of the largest intercooler cores available for the G3 WRX, measuring:

  • 400mm flow length
  • 205mm stack height
  • 120mm thickness

This large, free-flowing Process West core increases cooling capacity while maintaining efficient airflow through the system.


Complete Installation Kit

True to Process West design, this kit includes everything required for installation:

  • Verti-Cooler intercooler core
  • Custom under-hood duct / splitter system
  • High-quality silicone hoses
  • Constant tension hose clamps
  • All necessary hardware

Performance Benefits:

  • Dramatically reduces heat soak
  • Improves cooling efficiency under sustained load
  • Increases power consistency and throttle response
  • Enhances engine reliability and durability
  • Ideal for high-performance and track applications

An optional hot side silicone hose is available for compatibility with traditional non-stock turbochargers.

Big ol Toppy

I love this intercooler. Looks good and is bigger in person than in the photos. The install was pretty simple and straight forward. Only thing for me was the the stock bypass valve rubbed against the hose that went to the brake cylinder (circled in the picture) and caused a lot of vibration through the gas and clutch pedals. It took a while for me to figure it out so hopefully this helps the next person. The fix is to get a smaller bypass valve. I got the TurboSmart Kompact BPV and it fits perfectly as you can see in the picture.

This thing is massive

I did not expect this intercooler to be so big, but it fits perfect and looks great. If you need to have a bung welded on for an iat sensor the vht wrinkle black is a near perfect match.

Great product

Pros: chunky tmic, looks great, hard to heat soak but it will happen.

Cons: not all bov/bpv will fit on USDM due to the brake master cylinder. Get a turbo smart kompact bpv.

Suggestions - do your pitchstop mount while you're in there and have spare plastic clips

Awesome product

You get everything you need to install this. It’s like 3 x the side of the original Intercooler and makes a huge difference. I went with this over front mount because I think it make the engine look cleaner and also no turbo lag.

Awesome Product

fairly easy install, probably should’ve bought more plastic clips because i broke 90% of the original ones. overall only took me about 2 hours to get everything to fit right and tighten down. looks giant compared to the stock tmic, definitely a needed upgrade if you’re shooting for 400whp

Great product! Massive!

I could go on about how great this product is. How the welds are perfect, the finish is amazing, all the parts are correct, and the new hood scoop diffuser is absolutely amazing, but that’s not what I’m going to do. Let me tell you this. If you have done, or are going to do an STi 6 speed swap, the bracket that mounts to the transmission WILL NOT WORK. What comes with the kit mounts to the 5-speed. It does not bolt on to the pitch mount, but the bracket under the pitch mount. You need to get part number PWBRKT001 from Process West. That will make it work with the 6 speed. Otherwise, do what everyone else says, and keep everything loose until you have all the pieces in the right place, then tighten everything up. Once it’s done, it’s amazing! It looks outstanding, and the cooling efficiency is unbelievable. Hands down a great product! Installation doesn’t take too long. Just be patient. Overall, I love it.

Great design!

I really love this intercooler. It's like 4 times bigger than the stock WRX intercooler but fits great. I didn't have any issues installing it. One draw back of TMIC is that in order to work on the car you have to take it off just about every time, but its so easy to remove and reinstall that it really isn't and issue. You may need a little bit of extra slack if you have or plan on installing an IAG AOS. Since this thing is so big it's a little in the way of the hoses. performance wise its great. lots of room for air to circulate. the increased angle definitely forces more air through it. I installed this at the same time as ELHs (and supporting mods like injectors and fuel pump etc...) and my torque jumped to 350 at the wheels. It also looks awesome.
