Performance Gain: 15–18 hp, 12–16 ft-lb
The Mercedes M139 intake for the A45 and CLA45 was developed to provide a smoother airflow path to the turbocharger. By redesigning the system to ensure a more direct airflow path, the turbocharger can generate boost with less resistance, allowing it to reach target boost pressures earlier in the RPM range. This intake system was developed to achieve maximum flow while keeping intake temperatures as low as possible, resulting in pure performance gains. With the reduction in flow path restrictions, the turbocharger's spooling sound is also more audible, enhancing the overall driving experience.
Eventuri Features
The AMG M139 Eventuri system utilizes a patented carbon fiber housing and a Gen 2 specific filter to provide an aerodynamically efficient airflow path from the filter to the turbocharger. This is not just a cone filter with a heat shield; it is a unique design that induces a Venturi effect and maintains laminar flow to reduce turbocharger drag.

Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-Ya Shopping Site, we pay the import consumption tax incurred during customs clearance on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
As all product databases are based on North American vehicles (USDM), please verify whether the product can be installed on Japanese market vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility issues.
Please note that even if products are filtered by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not guarantee a direct fit for Japanese models without modifications.
All products are 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 payment. 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 cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please order with sufficient lead time. If you are in a hurry, please contact us in advance to check delivery times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese Vehicle Inspection (Shaken) standards," and we are unable to provide strength calculation documents or similar paperwork for these regulations. Therefore, all parts are sold for "track, private property, or off-road use only," and installation and usage are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only handle returns, refunds, or replacements for products with shipping damage, defects, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
