Treadstone Subaru STi Intercooler

  Front mount intercoolers for your WRX: massive 4.5" deep core, 28" long and 10.5" high making this the new benchmark intercooler! Capable of flowing 938cfm at 1.5psi pressure loss, this unit is efficient up to 900hp without breaking a sweat! With many of our private label intercoolers already on the market today, this unit is tried and tested on the track and the strip by many of the top names in Subaru tuning. The Treadstone name has become synonymous with quality intercoolers over the past few years, and we pride our selves on it! We manufacture our bar and plate cores with strict guidelines, and are specifically designed to maximize cooling using the most surface area possible in any given space. Our cores give the perfect balance between heat exchanging efficiency and flow. Our internal fin structure design is top notch, and is where the most important changes can be made to enhance the cooling rate. Treadstone intercooler cores feature a high heat-dissipating "Inner fin" design. This is ideal for medium to high boost levels on higher horsepower or upgraded turbo engines. The larger internal surface area provides superior cooling efficiency for radiating excessive heat and minimizing heat soak. In general, these design characteristics is what gives Treadstone Intercoolers the leading edge in intercooler technology
