AEM Cold Air Intake System for 2011-2014 Hyundai Sonata/Kia Optima 2.4L L4

AEM Cold Air Intake Systems are designed to increase horsepower and torque. They replace your vehicle's restrictive factory air box and air filter, resulting in improved performance and engine sound. AEM Cold Air Intakes relocate the air filter outside of the engine bay, allowing the engine to draw in cooler air. Because cold air is denser and contains more oxygen, it creates a more powerful combustion in the cylinders, producing more horsepower and torque. AEM Cold Air Intakes utilize a large, synthetic, washable AEM Dryflow air filter, which provides excellent airflow, filtration, and performance while allowing for easy, oil-free cleaning. They use mandrel-bent aluminum intake tubes and high-quality hardware to reduce restriction and lower intake temperatures. Since the design and components of each intake system vary, please refer to the installation instructions for the specific contents of each part number. This air intake is not legal for sale or use in California or other states that have adopted California emission standards.

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 there will be no additional charges beyond the total amount paid at checkout.

〇Compatibility Check
Our entire product database is based on North American vehicles (USDM). Please confirm whether the product can be installed on a Japanese model (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 check it for you.)
We cannot accept returns due to incompatibility if you place an order without confirming compatibility.
Please note that even if items are sorted by selecting the year, make, and model on our homepage tabs, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions are translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.

○ Regarding Shipping
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 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 plenty of time for your order to arrive. If you are in a hurry, please contact us to confirm the delivery time in advance. Please note that all products are transported by air; they are never shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspections (Shaken)
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection (Shaken) standards," and we are unable to provide strength calculation documents or similar paperwork for these inspections. 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 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 replacements for damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan for these matters.
