Fits:

• 2016-2021 Honda Civic 2.0L Non-Turbo (Coupe FC4, Hatch FK7, Sedan FC2)

The K20C2 is port injected, which already keeps the intake valves cleaner than a direct-injection-only setup, but there's still plenty of oil vapor getting pulled from the crankcase into the intake tract. That vapor coats the intake manifold and runners, and it lowers the effective octane of whatever fuel you're running — not what you want if you're chasing consistent, knock-free performance. This catch can intercepts it before it gets that far, using a diverter plate and triple-baffle design to separate oil from the vacuum-line airflow instead of letting it pass straight through.

It's a straightforward bolt-on install with no tuning required, and it's compatible with firewall-mounted flex fuel kits if you're running one. Everything needed for the install is in the box.
