As the perfect addition to the G9X M5 Intake System, this optimizes the flow path to the turbos. The stock inlets narrow immediately after the intake connection, which can restrict intake air volume, particularly under high boost pressure. Our carbon fiber inlets address this limitation by maintaining a constant, larger cross-sectional area, capturing more air right before the turbo. Furthermore, by optimizing the curvature of the inlet, we minimize flow resistance and promote smoother airflow to the turbochargers. Crafted from pre-preg carbon fiber with CNC-machined flanges, these inlets also enhance the aesthetics of the engine bay.
The benefits of these inlets are most apparent in tuned vehicles running higher boost pressures where the flow demands from the turbos are greater. In these cases, the larger inlet volume helps secure this additional flow.
This performance gain is achieved by reducing flow resistance to the turbo, allowing for quicker peak boost attainment in the high RPM range. The difference compared to the stock inlets is clear: while stock tubes narrow immediately after connecting to the intake, our tubes maintain a larger diameter, transitioning down to the stock turbo via the inner diameter of the machined flange. This maintains a smooth flow path while ensuring greater volume. A drawback of some oversized inlets is that they restrict flow because they are significantly reduced to match the stock turbo; our design avoids this.
Note: Some photos show the G9X M5 Intake System, which is sold separately as an option.
Each inlet set includes:
- Pair of pre-preg carbon inlets
- CNC-machined turbo flanges
- CNC-machined breather valve assemblies
Before You Order
〇 Regarding Import Duties
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of importation, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicle specifications (USDM). Please confirm whether the product is compatible with Japanese domestic market (JDM) vehicles before placing your order. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; our support team will be happy to assist you.)
If an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is displayed after sorting by year, manufacturer, and model using the tabs on our top page, it does not necessarily guarantee that the product will fit Japanese market 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 once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when placing your order. If you are in a hurry, please contact us in advance to confirm delivery times. All items are transported via air freight; they are not shipped via 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 the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for these regulations. 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 of your order immediately upon arrival. Since all products are shipped internationally from outside of Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for shipping-damaged, defective, or incorrect items if notified within 7 days of receipt. Please also note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not coordinate with other companies or agencies located within Japan.
