The Moroso billet aluminum small-body air/oil separator catch can for 2004–2007 Subaru STI and 2006–2007 WRX captures oil and vapors before they reach the intake. Its compact design fits the constrained engine bays of these models and helps reduce intake contamination and deposit formation on turbocharged engines. Machined aluminum construction provides durable separation performance.
