Dual catch can kit for the 2017+ Honda Civic Type-R (FK8 and FL5). Includes two catch cans: one for the PCV line and one for the crankcase vent line. Features Radium's patented Fluid Lock catch cans.
Product Overview
A catch can is a system that separates oil mist and moisture contained in the blow-by gas generated inside the crankcase, preventing them from accumulating in the intake manifold. It prevents oil adhesion and pooling in the intake, intercooler, throttle body, and intake manifold.
By keeping the intake air clean, it provides the following benefits:
Increased effective octane rating
Maintenance/improvement of engine performance and response
Additionally, because this product is a sealed system, it prevents oil odors originating from the crankcase from entering the vehicle cabin. The kit includes all necessary parts for installation.
About Radium Engineering's Patented Fluid Lock® Catch Can
Since 2022, Radium Engineering has incorporated a patented "Fluid Lock®" structure into its 7-ounce (approx. 207ml) catch cans.
Conventional catch cans had the problem of oil backing up and flowing back into the intake if periodic maintenance (draining the oil) was neglected.
Fluid Lock® is a mechanism that prevents overflow even if the inside of the tank is full, ensuring that accumulated liquid is trapped.
This prevents engine performance degradation even during long-term use.
Features
Large diameter 10AN ORB inlet/outlet
Equipped with 4AN ORB drain port
Two-stage oil separation baffle structure
Level gauge with O-ring seal for easy level checking
Capacity: 7 ounces (approx. 207ml)
Built-in patented Fluid Lock® mechanism
Maintenance
The amount of oil collected in the catch can depends on the vehicle condition and usage.
After installation, please check the remaining level with the level gauge after 3–4 weeks of driving to determine the appropriate oil draining schedule for your vehicle.
Oil draining method:
Remove the bottom part of the tank and drain (it can be easily removed by unscrewing).
Easy drainage is also possible by using the optional petcock drain kit.
Examples of excessive oil accumulation inside the tank:
Increased blow-by due to engine wear
Overfilling engine oil
Defective PCV valve
Breather design / lack of baffling
Dual Catch Can Kit
For maximum engine protection,
by combining two catch cans—one for the PCV line and one for the CCV line—you can keep intake air clean at all times, from low to high loads.

Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is sorted by selecting the year, manufacturer, and vehicle model using the tabs on our homepage, it does not necessarily mean it will fit a Japanese-market vehicle without modifications.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Estimates for shipping can be calculated automatically by entering your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you via email separately.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes about 7 to 14 days, so please allow plenty of time for delivery. If you are in a rush, please inquire about delivery times in advance. All products are shipped via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection System," and we cannot provide structural examination documents for the Japanese vehicle inspection system. Therefore, all parts are sold for "circuit, private property, or off-road use" only, and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. In cases of shipping damage, defective products, or items different from what was ordered, we will provide returns, refunds, or exchanges only if notified within 7 days of receipt. Please understand that for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
