The Process West Verticooler is a revolutionary departure from traditional intercooler design. By rethinking the mounting angle and airflow path, the Verticooler delivers a level of cooling efficiency and engine durability previously unseen in the Subaru aftermarket.

The Problem: The "Traffic Jam" effect

Stock top-mount intercoolers (TMIC) suffer from a lack of exit airflow. Computer modeling shows that once air passes through a factory-style core, it hits the engine block and creates a "traffic jam" of hot air. This trapped heat leads to rapid heat soak, significantly reducing performance during spirited driving.

The Solution: Verticooler Technology

The Verticooler system solves the heat soak issue by mounting the core at a 15-degree, near-vertical angle. This unique orientation provides several key advantages:

Optimised Exit Path: Heated air is forced down through the engine bay and out through the transmission tunnel, creating a low-restriction path that keeps the core cool.

Massive Core Volume: Featuring the largest volume of any aftermarket intercooler for this platform, the core measures 400mm x 205mm x 120mm.

High-Velocity Ducting: Includes a vehicle-specific under-hood duct that force-feeds fresh air directly into the intercooler fins.

Performance Benefits

Superior Cooling: Rapidly lowers intake air temperatures for consistent power delivery.

Flow Efficiency: Provides a shallower, less restrictive air path compared to the 90-degree turns required by stock setups.

Increased Durability: Lower IATs reduce the risk of engine knock, protecting your FA/EJ engine under load.

Complete Installation Kit

Process West provides a comprehensive "bolt-on" package containing everything required for a professional installation:

Verticooler Intercooler Core

Application-Specific Under-Hood Air Duct/Splitter

Specially Formed Silicone Hoses

High-Quality Constant Tension Hose Clamps

Turbo Versatility: An optional silicone hose is available for those running traditional tube-style outlet turbochargers, allowing for seamless integration with non-stock setups.

Taking a fresh approach formed from years of motorsport and component design experience, Process West are proud to announce the new ‘Verti-Cooler’ slant mount intercooler system of the G3 series (2008-2014) WRX. Designed and engineered with rapid air-charge cooling and flow-path efficiency as the key objectives, Verti-Cooler is a revolutionary take on Subaru intercooler design that takes turbocharger cooling to a new and previously un-seen level, guaranteeing the best performance and improved engine durability.

ORIGINAL INTERCOOLING
Computer modeling and real world testing of the factory Subaru Top Mount Intercooler shows that while cooling effectively in short bursts, a lack of exit air path from the bottom side of the intercooler creates a virtual ‘traffic jam’ of hot air in the engine bay which rapidly reduces intercooler efficiency in demanding conditions. Making the stock mount intercooler larger does improve the rate at which heat-soak occurs but does little to address the critical factor of getting the heated air away from the intercooler body itself.

VERTI-COOLER ADVANTAGE
Verti-Cooler combines the advantages of a large and free-flowing Process West core (400mm flow length, 205mm stack height, 120mm thick) with a design that mounts the new intercooler at a 15 degree, near vertical angle in the engine bay.

Packaged with a new hood duct design that force-feeds external airflow straight onto the intercooler fins, there is now a highly efficient air exit path courtesy of the Verti-Cooler mounting angle that flows all of this (now heated) air back down through the engine bay and out the underside of the car through the transmission tunnel for a shallow, cool, and low restriction exit-path.

Compare then the near on 90 degree angle that the air must turn with the stock intercooler setup in place, and the advantages of the Process West Verti-Cooler design become clear.

Verti-cooler also has the largest volume of any aftermarket intercooler for the G3 WRX with core measurements of 400mm flow length x 205mm stack height x 120mm thick.

Verticooler Kit - Subaru 15-21 VA WRX

$1,610.00 AUD

The Process West Verticooler represents a total rethink of Subaru cooling. Born from years of motorsport expertise, the Verticooler’s unique "slant-mount" design solves the inherent flaws of the traditional top-mount intercooler (TMIC), providing a level of cooling efficiency usually reserved for front-mount systems.

The Problem: The "Traffic Jam" Effect

The factory TMIC sits horizontally on top of the engine. While it works for short bursts, the heated air passing through it has nowhere to go but directly onto the hot engine block. This creates a "traffic jam" of hot air in the engine bay, leading to rapid heat soak and a significant drop in power during spirited or track driving.

The Solution: The Verticooler Advantage

The Verticooler solves this by mounting a massive, free-flowing core at a 15-degree, near-vertical angle. This orientation transforms how air moves through your engine bay:

Optimised Exit Path: Instead of trapping heat, the angled core allows air to flow naturally down through the engine bay and out through the transmission tunnel.
High-Velocity Airflow: A vehicle-specific hood duct force-feeds fresh, ambient air directly into the fins, maintaining high air velocity for maximum heat exchange.
Massive Core Volume: The Verticooler boasts one of the largest volumes on the market, featuring core measurements of 400mm flow length x 205mm stack height x 120mm thick.

Performance & Reliability

By drastically lowering intake air temperatures (IATs), the Verticooler ensures your FA20 engine stays within its safe operating window. You’ll experience more consistent throttle response, sustained boost levels, and improved engine longevity—even in demanding conditions.

What’s Included

The Verticooler arrives as a complete, comprehensive kit for a professional installation:

Verticooler Core (Available in Satin Black or Silver finish)
Application-Specific Hood Duct & Splitter
Specially Formed Silicone Hoses
High-Quality Constant Tension Hose Clamps

Custom Setup? An optional silicone hose is available for drivers running traditional "tube-style" outlet turbochargers, ensuring a perfect fit regardless of your turbo configuration.

TRACK TESTING

A hard test session was carried out at Australia’s Regional Wakefield Park Racing circuit. Although being a very cold day… about 14C in ambient temperature a series of rigorous tests were carried out in an attempt to pile on the heat.

Scheduled testing of 7 – 10 minutes at a time of flat out operation is enough to see the factory cooler heat-soaked and the intake temps start to rocket, but the Verticooler equipped MY15 pegged the inlet at no more than 23C

Any way you look at that data it’s a delta temperature change of only 9 degrees celcius, which is in fact the kind of temp gain you would normally expect to see in a normally aspirated application! Don’t believe it? Well as they say ‘The data never lies’ and we have included the raw testing to show you how good Verticooler really is!

DYNO TESTING
Once we felt – and measured – how good the Verticooler system was on the track it was time to see how the numbers stacked up on the dyno. The procedure went like this -
First was baseline testing

Car was stock with a cat back exhaust… pink line
We then tuned the car with stock intercooler… green line
Verticooler was then installed and allowed a much more aggressive timing map and increased boost… red line

Graph shows power/boost pressure

Graph shows power/torque

We also performed 3 back to back dyno pulls in quick sucession.

The Stock intercooler saw outlet temps quickly rise to 51 degee C.

Verticooler kept temps indefinitely under control with max outlet temp of 26 C.

It’s also worth noting that this testing was done in the midst of winter here in Australia.

Expect a much larger performance difference between the stock intercooler and Verticooler in the heat of summer.
