The AEM 21-836WR Performance Cold 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 Subaru WRX STI 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 location 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 constructed from mandrel-bent aluminum with a durable, textured red powder-coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices, including the mass airflow sensor. The conical AEM Dryflow air filter is made of an oil-free, synthetic filter material that can be used for up to 100,000 miles (approx. 160,900 km) without cleaning, depending on driving conditions. The air intake system is easy to install with common tools and comes with AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are legal in all 50 states. Please refer to the vehicle application information for the 21-836WR to determine the legal status for each vehicle.


Before You Order

〇 Regarding Import Consumption Tax
At Shaftoya 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.

Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please verify whether or not the product can be installed on a Japanese vehicle (JDM) 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 check 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 on the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.

○ Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate for shipping costs will be calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.

Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air. They are never shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength study documents or the like for Japanese vehicle inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, and off-road," and please install and use them at your own risk.

○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that for products with shipping damage, defective products, or products different from what was ordered, we will only handle returns, refunds, or exchanges if contacted within 7 days of receipt. Please note that regarding products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
