The 21-821DS Performance Cold Air Intake System increases horsepower and torque by replacing the restrictive air filter and air intake housing. This air intake system is designed, tuned, and dyno-tested for specific Nissan 370Z models. This system replaces both the left and right side intakes. The AEM Dryflow synthetic washable air filter does not require oil and can be used for up to 100,000 miles (approx. 160,934 km) depending on driving conditions. The heat shield features a two-piece design and utilizes the factory air ducts. The intake tubes are made of mandrel-bent aluminum with a durable gray powder-coated finish. This air intake system was developed to accommodate the mass air flow sensor and PCV hoses. The air intake system is covered by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting similar emission standards, while others are 50-state legal. Please refer to the 21-821DS application chart for the legality of each vehicle.


Before Ordering

〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.

Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese vehicle (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 investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using 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 Delivery
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when 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 individually via email.

All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air mail. They will not be shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not adapted to the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, 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, the packaging box or the product itself may have sustained damage during transit. Please understand that we will only provide returns, refunds, or replacement exchanges for products with transit damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please also note that for products sold through our company, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
