The AEM 21-759C 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 Lexus IS250 and IS350 models. Air is directed into the system through an oversized AEM Dryflow synthetic washable air filter, which provides exceptional 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 constructed from mandrel-bent aluminum with a durable gunmetal gray powder-coat finish. This air intake system was developed to accommodate the factory engine's emissions control devices, including the mass air flow sensor and PCV hose. The tapered cylindrical AEM Dryflow air filter is made from an oil-free synthetic filter media that can be used for up to 100,000 miles without cleaning (depending on driving conditions). The air intake system is easy to install using common tools. Please note that while some AEM air intakes are not legal for sale or use in California and other states adopting California emissions standards, others are 50-state legal. Check the vehicle application guide (21-759C) to verify the legal status for each vehicle.
Before Ordering
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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
As our entire product database is based on North American vehicles (USDM), please verify whether the product 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 look into it 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 top page, it does not necessarily guarantee that they will fit Japanese market models 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 costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. In rare cases, there may be a significant difference between the automatically calculated shipping cost and the actual shipping cost for large items such as body parts. 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 approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are basically all designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we are unable to provide strength study reports or similar documentation for this system. Therefore, all parts are sold for the purpose of "use on circuits, private property, and off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement products for damaged, defective, or incorrect items if you notify us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
