The original OEM B58 heat exchanger is a 27mm thick, single-row unit. By comparison, CSF uses the world's largest 2-row core (68mm) exclusive to the industry, along with CSF's B-Tube technology. A unique tank design allows the larger CSF core to fit into the OEM cooling system housing. Another key feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. Water passing through the upgraded heat exchanger flows through the radiator three times before leaving the cooler and returning to the manifold charge cooler. This ensures the lowest possible outlet water temperature from the heat exchanger. All OEM designs and more expensive aftermarket designs feature a single-pass flow structure.

Before Ordering

〇Regarding Import Consumption Tax
At Shafto-ya Shopping, we pay the import consumption tax incurred during import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

〇Checking Compatibility
All product databases are primarily based on North American vehicles (USDM). Please confirm whether the part is compatible with Japanese market vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model using the tabs on our top page, this does not necessarily mean they will fit Japanese market vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so 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 once you enter 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 individually.

In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are not shipped by sea.

○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we are unable to provide strength calculation reports or similar documentation for Japanese inspections. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.

○Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Please note that for products sold through us, warranty-related support is provided "only through us." We do not provide support through other companies or distributors located in Japan.
