2013+ Ford Focus EcoBoost Catch Can Kits by Radium Engineering

The Radium Engineering catch can kits are among the most functional and integrated kits on the market. The catch cans mount using factory holes and integrate perfectly with the surrounding components. The two oil catch cans (PCV side and Crankcase side) function completely independent of each other and are sold individually or together. They do NOT vent to atmosphere (VTA), thus are emissions and track legal.

Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. No cutting, drilling or permanent modification to the vehicle is required.


  • Effectively raises the octane and increased engine performance from cleaner inlet air
  • Prevents oil buildup in the intake and intercooler system walls, throttle body, intake manifold, etc.
  • Lowers hydrocarbon emissions

Please Note:

  • The crankcase style is only compatible with RS models

Easy install and does it's job in style

Install was very straightforward, plus it adds a nice touch out in the open on the core support. Has also reduced build up on valves

Needs to be a package deal.

I was eager to install this otherwise awesome set of catch cans, however it was unknown to me that for the Focus ST you need to ๐š๐ฅ๐ฌ๐จ ๐›๐ฎ๐ฒ ๐š ๐ฌ๐จ๐ฎ๐ง๐ ๐ฌ๐ฒ๐ฆ๐ฉ๐จ๐ฌ๐ž๐ซ ๐๐ž๐ฅ๐ž๐ญ๐ž ๐ค๐ข๐ญ. Also the hose clamps that come with the kit for the 3/8 in. hose doesn't actually fit around the hose while its attached to the PCV valve fitting would recommend to the company that they fix that because this is apparently a well known issue and hasn't been fixed yet. Relatively easy installation would recommend this kit to anyone who has a Focus ST.

The quality and ease of install were my favorite parts of this cat h can. I have one for the crankcase side and I purchased the PCV side this time. Works amazing, within the second day it had already started doing it's job! Shipping was fast and no hassle. If you have a focus RS or ST definitely consider the radium catch can!

Brian Kozerski
Excellent quality

Radium makes a top notch product using quality materials and engineering I have both the pcv and crank case catch cans on my ecoboost mustang. Some creative lication finding is essential being that the brackets are for the RS focus but the donwork and fit just fine

Radium catch can focus st

Part arrived extremely quickly....fit and quality was amazing, only problem I ran into was the top bolt seeping vapor, just have to torque it down really tight and you'll be good to go, you will not be disappointed with this can!
