The Subaru WRX is a performance-oriented vehicle that benefits significantly from upgrades, particularly in its intercooling system. One of the most effective upgrades for enhancing power and efficiency is the installation of a top mount intercooler (TMIC). This article explores three leading brands in the market: Garrett, Spulen, and AMS. We will compare their features, benefits, and potential power gains to help you make an informed decision.
Understanding Top Mount Intercoolers
Top mount intercoolers are designed to cool the intake air coming from the turbocharger before it enters the engine. They play a crucial role in maintaining optimal performance by reducing intake temperatures, which can lead to better combustion and increased horsepower. When selecting a TMIC, it’s essential to consider factors such as core size, material, and design.
