AEM Nissan Frontier/Pathfinder/Xterra 4.0L Silver Brute Force Air Intake

The AEM 21-8504DC Brute Force Air Intake System increases horsepower and torque by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system is designed, tuned, and dyno-tested to fit specific Nissan Frontier, Xterra, and Pathfinder models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter, which provides excellent airflow, filtration, and performance. The air filter is placed in the space of the factory air box and is protected by a heat shield designed to reduce intake air temperature and increase horsepower. The intake tube is manufactured from mandrel-bent aluminum and finished with a durable gunmetal gray powder coating. This air intake system is developed to accommodate the engine's factory emissions control devices, including the mass air flow sensor and crankcase vent hose. The conical AEM Dryflow air filter is made from oil-free synthetic filter media and can be used for up to 100,000 miles (approx. 160,934 km) without cleaning, depending on driving conditions. This air intake system installs easily with common tools and is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes may not be legal for sale or use in California and other states adopting California emissions standards, while other products are 50-state legal. Please check the vehicle application information for the 21-8504DC to confirm the legal status for your specific vehicle.

Before Ordering

〇 Regarding Import Consumption Tax
At 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.

〇Confirmation of Compatibility
All of our product databases are based on North American vehicles (USDM), so please verify whether the item can be installed on a Japanese domestic vehicle (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.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our home page, this does not necessarily mean they will fit Japanese model vehicles without modification.
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 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 amount calculated automatically. In such cases, we will contact you individually via email.

Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They are not shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we carry are basically all designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork 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 of your order immediately upon arrival. As all products are shipped internationally from outside 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 replacements for damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please be aware that we do not provide support through other companies or distributors located within Japan.
