PRODUCT DETAILS
This is the Moroso Air-Oil Separator Kit. The intended purpose of this system is to keep the excess crankcase vapors, residual oil, and moisture from building inside the intake manifold and to more importantly, keep the factory crankcase ventilation system from adding a layer of oil which can cause detonation issues. The provided tank will capture any excess oil and fluids and will prevent them from entering your intake system.
This kit features a billet aluminum tank, and this kit will come with all the required hardware, brackets, fittings, and hoses to make for a ready installation. The tank will come in a nice raw aluminum finish to add a cleaner look to the engine bay. This is a great way to keep your factory crankcase ventilation operating how it has been designed.
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
