Show original supplier description
The GrimmSpeed Top Mount Intercooler (TMIC) Splitter is engineered to enhance the cooling performance of your 2006-2007 Subaru WRX or STI. This splitter offers a 70% increase in flow capacity to the TMIC, significantly improving its heat removal capabilities and maximizing efficiency. By ensuring even flow distribution across the entire intercooler core, it lowers TMIC outlet temperatures, which in turn enables more aggressive tuning. The splitter is constructed from CNC laser-cut 5052 Aluminum, chosen for its resistance to fatigue from heat and vibration, and features a durable DuPont black powdercoat for an OEM finish. A custom EPDM rubber gasket provides an excellent seal and longevity. Additionally, it includes 3x Intercooler Sprayer Ports, allowing for the utilization of the factory STI TMIC sprayer or the addition of a new one. This product is specifically designed to fit the 2006-2007 Subaru WRX and 2006-2007 Subaru STI models equipped with the OEM WRX/STI 06-07 Hood Scoop.
