The all-new HPS Performance 837 Series Cold Air Intake Kit (Red, Part Number 837-508R) for the 2011-2016 Scion tC features a free-flowing 3-inch mandrel-bent aluminum tubing induction system that relocates the HPS Performance air filter outside the engine compartment to provide the coolest possible intake temperatures. Compared to conventional intake setups, the HPS Performance 837 Series Cold Air Intake Kit delivers cooler, oxygen-rich air. This results in increased horsepower, torque, and improved throttle response through stronger combustion within the vehicle's cylinders, while maintaining a safe air-fuel ratio. The included installation manual features clear photos and instructions to guide the installer through the entire process. Re-tuning is required, but it will not trigger a CEL (Check Engine Light). No modifications are necessary during installation.

Before Ordering
〇 Regarding Import Duties
At the Shaftoya shopping site, we pay the import duties incurred during customs clearance on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American (USDM) vehicles; please verify compatibility with Japanese (JDM) vehicles 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 be happy to investigate.)
If an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model using the tabs on our top page, this does not guarantee a direct fitment for Japanese-market models without modification.
All products have been translated into Japanese using translation software. Due to potentially confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping fees are paid at the time of checkout. Shipping cost estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping fee may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please allow sufficient time for your order. If you are in a hurry, please contact us for an estimated delivery time in advance. All products are transported via air freight; no shipments are made via sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Products handled by our company are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for Japanese inspection purposes. 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, packaging and products may occasionally sustain shipping damage. We will only provide returns, refunds, or replacement exchanges for damaged, defective, or incorrect items if notified within 7 days of receipt. Please understand that for products sold through our company, all warranty claims must be handled "exclusively through our company." We do not provide support through other companies or distributors located within Japan.
