The AEM cold air intake for 08-14 Subaru WRX / STI is a great way to get a cooler & denser air charge into your engine. This intake system produces estimated gains of 36 hp. AEM has designed this intake to retain the stock diameter MAF housing and features a built in air straightener to ensure the MAF sensor readings are accurate & will not cause a check engine light. This intake features a 9 inch dryflow air filter to ensure the MAF sensor does not get gummed up which is common with oiled filters. The included heat shield ensures the intake will be inducting a nice cool air charge drawn from the fender.
