The Moroso air/oil separator catch can for 2008–2014 Subaru WRX STI with a top‑mount intercooler is a billet‑aluminum can that diverts oil and crankcase vapor away from the intake. It provides a cleanable collection chamber and a compact footprint for engine bays with top intercoolers, helping maintain intake cleanliness and reduce oil deposits over time without altering factory routing.
