Radium Engineering Catch Can Kit – Toyota GR Corolla (2023+)

Description

The Radium Engineering Catch Can Kit for the Toyota GR Corolla is a high-performance crankcase ventilation upgrade designed to reduce oil contamination in the intake system, improve engine reliability, and maintain consistent performance under boost.

During normal engine operation, oil vapor and moisture are pushed through the crankcase ventilation system and routed back into the intake tract. Over time, these contaminants can build up in the turbocharger inlet, intercooler, throttle body, and intake manifold. A properly designed catch can captures these vapors before they enter the intake, helping keep the air path clean and the engine operating more efficiently.

The Radium system is engineered specifically for the GR Corolla platform and installs as a direct bolt-on solution using factory mounting points. It integrates cleanly with the OEM crankcase ventilation system while providing motorsport-grade oil separation and long-term durability.

Unlike universal catch cans, the Radium kit uses platform-specific hoses, fittings, and brackets to ensure proper flow characteristics and OEM-level fitment. This makes it an ideal upgrade for daily-driven vehicles, tuned street builds, and track-focused GR Corolla setups.

How This Catch Can System Works

The Radium catch can kit captures oil vapor and moisture from crankcase gases before they are routed back into the intake system. This helps prevent oil buildup in the turbocharger, intercooler, intake manifold, and throttle body while promoting cleaner airflow and more consistent engine performance.

The system operates inline with the crankcase vent (CCV) circuit between the valve cover and turbo inlet, where oil vapor flow is highest under load. By filtering these gases, the catch can reduces contamination and helps maintain optimal combustion efficiency and long-term engine health.

Fluid Lock® Technology (Key Advantage)

Traditional catch cans can overflow if not serviced regularly, allowing collected oil to re-enter the intake system. Radium’s patented Fluid Lock® design prevents this by trapping collected fluids inside the reservoir and preventing them from being pushed back into the intake.

This design adds an extra layer of protection for performance engines, especially under high boost or extended track use.

Why Upgrade the GR Corolla Crankcase Ventilation System?

The factory crankcase ventilation system is designed for stock power levels and emissions compliance. As boost pressure, engine load, and driving intensity increase, oil vapor accumulation in the intake system becomes more significant.

Installing a high-quality catch can system provides:

• Reduced oil contamination in the intake tract

• Improved intercooler and throttle body cleanliness

• More consistent combustion and performance

• Increased reliability for tuned and high-boost builds

• Long-term engine protection

For GR Corolla owners planning performance upgrades, ethanol fueling, or track use, a catch can is one of the most effective preventative modifications available.

Radium vs OEM vs Universal Catch Can Systems

OEM Crankcase Ventilation

• No oil vapor separation

• Allows oil and moisture into the intake system

• Limited protection for performance applications

Universal Aftermarket Catch Cans

• Often require custom hose routing

• Inconsistent flow design

• Limited platform-specific engineering

Radium Engineering Catch Can Kit

• Designed specifically for the GR Corolla platform

• Direct bolt-on installation with OEM-style integration

• Motorsport-grade oil separation and durability

• Patented overflow prevention technology

Is This Upgrade Worth It for Daily Driving?

Yes. While catch cans are often associated with track builds, they also provide meaningful benefits for daily-driven GR Corollas.

Daily driving benefits include:

• Cleaner intake system over time

• Reduced oil residue in intercooler and intake manifold

• Improved long-term reliability

• Future-proofing for performance upgrades

Frequently Asked Questions

Does this catch can kit require modifications to install?
No. The Radium catch can kit is designed as a direct bolt-on system using factory mounting points and OEM-style connections.

How often should the catch can be emptied?
There is no fixed interval, as oil collection varies by vehicle and driving conditions. Radium recommends checking the catch can level periodically to determine the appropriate service interval.

Will this cause check engine lights?
In rare cases, certain aftermarket intake systems may trigger crankcase ventilation-related fault codes. This is uncommon when the engine and intake system are otherwise OEM.

Is this system suitable for track use?
Yes. The Radium catch can kit is designed to withstand high-load and high-boost driving conditions.

Does this improve horsepower?
While a catch can does not directly increase horsepower, it helps maintain consistent performance by keeping the intake system clean and reducing oil contamination.
