Increasing the intercooler surface area beyond that of the factory unit is all well and good but only if all of the ambient air is available to all of the upgrade intercooler so maximum heat exchange can take place. The answer here is of course a revised under bonnet duct.

The new Process West 04-09 Liberty GT Top Mount Intercooler addresses all of the above issues and it does it very well. Process West's new Top Mounted Intercooler is virtually a small front mounted intercooler mounted in the engine bay.

With a massive 400mm flow length (almost double the factory unit) and a not too thick 90mm bar and plate core an effective top mount is now here.

Details:

• Core Size: 400 x 198 x 90mm
• Strong & Durable Intercooler Hoses included
• Hood Splitter included

The goal when developing our new top mounted intercooler was to make it the very best aftermarket top mounted intercooler for the Forester.

We studied our competitors products and fixed all of the mistakes they have made...some of them major.

The most obvious error that every one of our competitors makes is not supplying their intercooler with proper ducting/shrouding to suit the increased size of the new intercooler. There is no point in installing a larger intercooler and leaving the factory under bonnet splitter/shroud in place. Here is the solution. A properly sized splitter/shroud to suit the application.

• Core Size: 490 x 193 x 90mm
• Silicone Y-Pipe
• Hood Splitter included

Taking a fresh approach formed from years of motorsport and component design experience, Process West are proud to announce the 'Verti-Cooler' slant mount intercooler system.

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.

The new Process West Front Mount Intercooler Kit for the 2015+ Subaru VA WRX allows for superior air intake cooling. This is achieved by using light-weight CNC mandrel bent aluminuim intercooler piping and a large 685 x 275 x 85mm bar & plate intercooler core. 

The beautiful thing about this front mount kit is that there is no cutting required in order to fit and install, and everything you need to complete install is included in the kit - i.e. hose clamps, intercooler brackets etc.

 Comes with a choice of a black powdercoat or silver finish.

Details:

• Core Size: 685 x 275 x 85mm
• Light weight CNC mandrel bent aluminium intercooler piping
• Hi flowing cast intercooler end tanks for maximum flow distribution across the intercooler core
• Stainless steel hose clamps
• Fits with zero cutting
• Intercooler core available in polished or black powder coated finish

The Process West Charge Pipe Kit for the 2015+ Subaru WRX, is the best upgrade charge pipe kit on the market.

Made in 2 pieces it is easy install, without the hassle of trying to feed one big pipe into position and includes all the necessary couplers and clamps for the perfect fitment. The charge pipe kit provides a much smoother air flow path from the turbo to the intercooler, over the factory pipe.

Finished in a nice black powdercoat, the upgrade doesn't look out of place, and gives a factory appearance.

Taking a fresh approach formed from years of motorsport and component design experience, Process West are proud to announce the new ‘Verticooler’ 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, Verticooler 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.

The Verticooler 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 Verticooler 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 Verticooler design become clear. 

Details:

• Core Size: 400 x 205 x 120mm
• Includes suitable Hood Splitter
• Reduces Heatsoak compared the factory Intercooler
