The Radium Engineering fuel filter kit is a bolt-on solution designed to replace the factory fuel filter in many Nissan vehicles with a high-performance microglass specification. It is compatible with a wide range of vehicles, including the S13 / S14 / S15 Silvia and the R32–R34 Skyline, and can be installed in the original filter location. No cutting or drilling is required; it uses the factory stud bolts for mounting, allowing installation to be completed with just a few wrenches.
Compared to the factory filter, this filter offers lower internal resistance, reducing the load on the fuel pump. This decreases current draw and stabilizes fuel supply while suppressing fuel temperature rise. It significantly contributes to improved reliability and performance, especially in competition vehicles driven under high-load and high-RPM conditions. It also supports race fuels such as methanol, ethanol, and E85, making it well-suited for modern tuning environments.
The filter element is available in your choice of *6-micron (microglass) or 10-micron (stainless steel) depending on your application. The housing, clamps, and brackets are all made from anodized billet aluminum, offering a balance of durability and light weight. The kit includes 6AN compatible large-bore hoses, fittings, and stainless steel bolts to provide a trouble-free, reliable fuel line. A 90-degree push-lock fitting for aftermarket fuel rails is also included.
This is an ideal upgrade for those seeking stable fuel pressure management, improved response, and reduced pump strain.
*The 6-micron (microglass) filter offers slightly lower internal resistance and better flow compared to the stainless steel filter, but it requires periodic replacement and cannot be cleaned and reused like the stainless steel version (disposable). The 10-micron (stainless steel) filter model (20-0585-03) can be maintained through periodic cleaning.
※ This kit includes a filter mounting bracket (part number 20-1585). (No separate purchase required)

Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya, we pay the import consumption tax incurred during customs clearance on your behalf. There will be no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm whether the product is compatible with Japanese domestic market (JDM) vehicles before ordering. (If you are unsure if a listed product fits 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 items are sorted by year, make, and model using the tabs on our homepage, it does not guarantee that they will fit Japanese model vehicles without modification.
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. Shipping estimates are calculated automatically on the checkout page after you enter your delivery address. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a rush, please contact us in advance to check the delivery time. Please note that all products are transported by air. They will not be shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are essentially designed and manufactured outside of Japan. Please be aware that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents for Japanese inspection purposes. Therefore, all parts are sold for "circuit, private property, or off-road use only," and their installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your package immediately upon arrival. As all products are shipped internationally from outside Japan, there may be instances of delivery damage to the shipping box or the product. We will only handle returns, refunds, or exchanges for products with delivery damage, defective goods, or items different from what was ordered if you notify us within 7 days of receipt. Please understand that for products sold through us, warranty support is handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
