Review RADIUM ENGINEERING Bmw Catch Can Kit Fluid Lock fits E46 M3

Introducing the Radium Engineering 20-0073-FL BMW E46 M3 Catch Can Kit with Fluid Lock Technology. This high-performance upgrade is designed specifically for BMW E46 M3 vehicles, providing an effective solution for reducing engine oil carryover and maintaining optimal engine performance.

The heart of this system is the compact and efficient catch can. Engineered to the highest standards, this catch can features a baffled design that maximizes the surface area of the internal walls, allowing for efficient separation of oil mist from the crankcase vent gases. The canister is constructed from 6061-T6 aluminum, offering robustness and durability, while its anodized finish ensures a long-lasting and attractive appearance.

One of the most innovative features of the Radium Engineering 20-0073-FL Catch Can Kit is the Fluid Lock Technology. This advanced system uses a one-way check valve to prevent the stored oil from being drained back into the crankcase during deceleration or when the engine is off. Instead, the oil remains in the canister, where it can be easily drained using the provided drain plug. This not only helps to reduce oil carryover but also prevents the contamination of fresh oil with used oil.

The kit includes all the necessary components for a straightforward installation. These include the catch can, mounting bracket, breather hoses with OEM-style fittings, and the Fluid Lock check valve. In addition, the installation process is simplified by the use of factory-style fittings, which minimize the need for modification to the engine bay.

The Radium Engineering 20-0073-FL BMW E46 M3 Catch Can Kit with Fluid Lock Technology is an essential upgrade for any BMW E46 M3 enthusiast looking to maximize engine performance and reduce oil consumption. With its robust design, advanced Fluid Lock Technology, and ease of installation, this catch can kit is a must-have for any serious BMW M3 owner.

5. Fluid Lock Technology: The Fluid Lock technology used in the catch can ensures that it is always full and functioning properly. This technology uses a one-way valve to prevent the can from draining when the engine is off.

Cons:

1. Cost: The Radium Engineering catch can kit is more expensive than some other aftermarket options. However, the high-quality materials and advanced technology used in the kit justify the higher price.

2. Maintenance: The catch can kit requires periodic maintenance, including checking and refilling the fluid level. This can be a inconvenience for some users.

3. Size: The size of the catch can kit may not be suitable for all applications. The kit is designed specifically for the BMW E46 M3, so it may not fit other vehicles.
