Built for performance and aesthetics, the HPS Black Cold Air Intake Kit for 2015-2016 Subaru Impreza WRX STI 2.5L Turbo relocates the HPS performance air filter outside the engine bay to provide the lowest possible intake temperatures. Compared to traditional short-ram air intakes, the HPS long-ram cold air intake delivers colder, oxygen-rich air, resulting in more powerful explosions in the vehicle's combustion chamber. This produces dyno-proven performance gains of +19.4 Whp and +20.5 ft/lbs of torque while maintaining a safe air-fuel ratio and improving throttle response. A heavy-duty powder-coated steel heat shield blocks hot air from the engine bay for maximum cooling. Included installation instructions guide you through the entire process. No tuning or modifications are necessary. The included air straightener minimizes the risk of a CEL light. HPS lightweight mandrel-bent aluminum alloy tubing replaces the restrictive stock airbox to optimize airflow with superior heat dissipation and long-lasting durability. The HPS cold air intake system features HPS's signature race-proven reinforced silicone hoses and industrial-grade 100% stainless steel T-bolt clamps for reliability in even the harshest driving conditions. The all-new HPS performance air filter is made in the USA and designed with performance in mind, providing superior filtration without sacrificing airflow. Washable and reusable. Not CARB compliant. Vehicle Application: 2015-2016 Subaru Impreza WRX STI 2.5L Turbo.
Before Ordering
〇Regarding Import Duties and Taxes
At the Shaftoya shopping site, we pay the import duties and taxes incurred during import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm whether the product is compatible with Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure if a listed product is compatible with your vehicle. Our support team will investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by year, manufacturer, and vehicle model using the tabs on our homepage, this does not guarantee that the product will fit Japanese 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when 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 automated calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they do not conform to the "Japanese vehicle inspection system," and we are unable to provide strength calculation documents or similar paperwork for these requirements. 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 of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of damage to the packaging or the product during transit. We will only provide returns, refunds, or replacements for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through our company, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
