Performance Gain: 15–18 whp, 15–16 ft-lb
The C8 Corvette HTC Eventuri intake sets a new benchmark for this platform by achieving the highest performance and maximum internal volume*. Because the size and shape of the intake were constrained by the factory trunk panel, we redesigned it to accommodate a larger intake. We incorporated a transparent polycarbonate section so the carbon intake is visible when the trunk is open. By utilizing our patented Venturi housing concept, the airflow path is significantly less tortuous, reducing system resistance as it passes through the filter. Furthermore, by increasing the total volume of the intake, we have improved flow rates to maximize performance even on high-power builds. By utilizing the factory air feed and using low-thermal-conductivity carbon fiber throughout, we have ensured a sealed system that minimizes intake temperatures. This system delivers industry-leading performance gains and a noticeable improvement in throttle response.
Each intake system includes:
- Carbon Fiber Dual Venturi Filter Housing
- Custom High-Flow Dry Cone Filter
- Carbon Fiber Inlet Duct
- Transparent Polycarbonate Trunk Panel
- Silicone Hose (with custom step-less transition)
- Laser-cut Stainless Steel Brackets and Heat Shield
- Custom Inlet Flange
- Custom Flexible Hose
Before You Order
〇 Regarding Import Consumption Tax
At Shafto-ya Shopping Site, we pay the import consumption tax incurred during customs clearance on your behalf; therefore, you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Compatibility Verification
Our product database is based on North American (USDM) vehicles. Please verify compatibility with Japanese (JDM) vehicles before placing your order. (If you are unsure whether the 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.
Please note that even if a product is sorted under your vehicle's year, make, and model using the tabs on our top page, it does not necessarily guarantee a direct fitment without modification for Japanese market models.
All products have been translated into Japanese using translation software. As there may be ambiguous expressions, please contact us with any questions before ordering.
○ 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 are rare instances where there is 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 7–14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us to confirm the delivery date in advance. All products are transported via air freight; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese Vehicle Inspection (Shaken) standards," and we cannot provide structural strength documentation or similar paperwork for the purpose of Japanese inspections. Therefore, all parts are sold for "track, 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. As all products are shipped internationally from outside Japan, there is a possibility of damage to the shipping box or product. We will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty support will be provided "exclusively through our company." We do not provide support through other companies or agencies located within Japan.
