The all-new HPS Performance 837 Series Cold Air Intake Kit (Black, Part Number 837-122WB) for 2004-2008 Acura TSX 2.4L provides a free-flowing 2-3/4" mandrel-bent aluminum tube induction system. It relocates the HPS Performance air filter outside of the engine bay to maintain the lowest possible intake temperatures. It can be converted to a short ram intake. Compared to conventional intake setups, the HPS Performance 837 Series Cold Air Intake Kit delivers cooler air with more oxygen, causing a more intense explosion in the vehicle's combustion chamber, resulting in dyno-proven performance gains - an increase of +11 whp and +9.9 lb-ft of torque while maintaining a safe air-fuel ratio, and improved throttle response. The included installation manual contains clear photos and instructions to guide the installer through the process. This kit does not require tuning and will not trigger a CEL light. No modifications are necessary during installation. HPS lightweight mandrel-bent aluminum alloy tubing replaces the restrictive stock air box to optimize airflow with superior heat dissipation and long-term durability.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
As our entire product database is based on North American vehicles (USDM), please confirm the compatibility for Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; 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 items are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our top page, this does not necessarily mean they 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 payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may rarely differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery dates. All products are transported via air freight. No products are shipped via sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents or similar paperwork for these standards. 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 may be shipping damage to the packaging or the product itself. Please understand that we will only handle returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through our company, warranty support will be provided "only through us." Please note that we do not provide support through other companies or distributors based in Japan.
