Catch Cans

Catch Cans: keep oil vapor out of your intake tract

A catch can sits in the crankcase ventilation line and does one job: it intercepts the oil mist, fuel vapor and moisture the PCV system pulls out of the crankcase before that gunk reaches your intake. On modern direct-injection engines there is no fuel washing the back of the valves, so those vapors bake onto the ports and choke airflow over time. A can lets the heavy stuff condense and drop into a reservoir you drain, keeping the intake and valves cleaner. Boosted and hard-run engines benefit most, since they push more blow-by. That is why catch cans are one of the first things people add to a build.

What we stock

This category holds 221 catch cans and kits from 9 brands. Mishimoto (85 products) and Radium Engineering (75) make up most of the range, followed by CORSA Performance, K&N Engineering, Vibrant, Cusco, Weapon R, Moroso and HKS. Current in-stock pricing runs from $26 to $1,268, which is the live range today, not a standing offer. At the top sits the HKS S-Type O/C kit for the FK8 Civic Type-R; multi-can setups like the Radium triple catch can kit for the 2014-2019 Corvette LT1 and the Radium dual kit for the R32 Skyline GT-R also live here.

How to choose

The main split is direct-fit versus universal. A direct-fit kit like the Mishimoto 370Z baffled can or the Mishimoto Powerstroke kit comes with vehicle-specific brackets and lines, so it bolts where it was designed to go. A universal breather tank like the Moroso 6in dual -16AN aluminum tank gives you flexibility to plumb your own routing, but you supply the fittings and mounting. Single cans handle a typical single-line PCV setup; dual and triple kits exist for engines with more than one ventilation source. Match inlet size and line count to what your engine actually runs, and buy the can with the brackets if you would rather not fabricate.

What else you need

Universal setups usually need plumbing to finish. Browse Fittings and Adapters to connect lines to the tank. While the intake tract is on your mind, Oil Filters and Gasket Kits round out routine engine work. See everything in the Engine Components section for related parts.

Fitment and ordering

Fitment data covers 158 of the 221 products, spanning model years 1983 to 2025.
