PDF - 2022+ Honda Civic 1.5T High Volume Intake System Installation Guide 
"Why didn't you design a Cobra-style cold air intake like you did for the 10th gen?"
Unlike the 10th Gen Civic 1.5T chassis, the 11th Gen / 5th Gen Integra features a fairly large and efficient air duct through the front bumper/grille from the factory. We decided to retain and utilize the factory air guides. In our HVI design, however, our engineers decided to take it a step further. To maximize airflow, our HVI comes standard with a proprietary injection-molded high-volume inlet duct that attaches to the airbox with OE-style clips and seals against the factory rubber seal/guide on the hood. We also offer a High Volume "Plus" Cold Air Intake Duct!
Important Notes:
- No ECU calibration required
- 10+ horsepower and torque increase!

Before Ordering
〇Regarding Import Consumption Tax
At Shafto-ya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
All of our product databases are based on North American vehicles (USDM). Please check whether the product can be installed on Japanese domestic vehicles (JDM) before ordering. (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 look it up 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, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean 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 fees are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may rarely be a significant discrepancy between the automatically calculated shipping fee and the actual shipping cost. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight. They are not shipped by sea freight.
○Regarding Japanese Vehicle Inspection Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese vehicle inspection standards," and we cannot issue documents such as strength calculation reports for Japanese vehicle inspection standards. 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 when the product arrives. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if contacted within 7 days of receipt. Please understand that for products sold through our company, we only provide support regarding warranties "through our company." Please note that we do not provide support through other companies or distributors located within Japan.
