What is the purpose of a catch can system?

A catch can system collects oil vapors and moisture from the crankcase ventilation system. This prevents these contaminants from being re-circulated into the intake manifold and combustion chamber, helping to keep engine components cleaner.

Does this kit include everything needed for installation?

The kit includes the dual Fluid Lock catch cans and components designed for installation on the 2015-2021 Subaru WRX. It is recommended to consult the manufacturer's installation guide for any additional tools or hardware that may be needed.

How often do I need to empty the catch cans?

The frequency of emptying depends on driving conditions and engine blow-by. It's generally recommended to check the cans every few thousand miles or when they appear to be about half full. Refer to the manufacturer's instructions for specific guidance.

Product Details

The Radium Engineering Fluid Lock catch cans are built with a patent-pending design to help manage oil blow-by in your 2015-2021 Subaru WRX. This dual kit is specifically made for the WRX platform, helping to keep your engine's intake system cleaner by capturing oil vapors before they can recirculate. Over time, these vapors can build up on intake valves and in the combustion chamber, potentially affecting performance and efficiency. By installing this kit, you're taking a proactive step to maintain your engine's health and performance.

This kit features Radium's Fluid Lock catch cans, which are designed for effective oil separation. The construction is solid, and the kit is designed to fit the specific layout of the 2015-2021 WRX engine bay. While it's a direct fit for most stock intake systems, it's always a good idea to check compatibility if you've installed an aftermarket intake, as those can sometimes alter the available space or mounting points. Installing a catch can system is a popular modification for WRX owners looking to protect their engines from the effects of direct injection and blow-by.
