About STI Top Mount Intercooler
The Subaru WRX STI is a turbocharged, high-performance model of the Impreza that first saw production in 2007. It uses an STI top-mount intercooler to help keep things under the hood cool while the turbocharger boosts the power of your Impreza engine. The intercooler sits between the turbocharger and the engine, providing a wide plate with fins to help spread out superheated air from the charger to reduce friction and lower the air temperature. Intercoolers are essential to turbocharger systems because they help prevent pre-detonation of fuel with the superheated, pressurized air. Using an STI OEM intercooler is also a less wasteful alternative to using extra fuel to cool the air before it enters the piston chambers. You can find an STI top-mount intercooler in the large inventory on eBay. If you prefer to seek out a used STI intercooler, it can help save you some cash on your repair and replacement efforts. These top-mount intercoolers sit top of your engine compartment and are plainly visible when you look under the hood. With an STI top-mount intercooler, you can keep that turbocharged system in top-condition.
