The all-new HPS Performance 837 Series Cold Air Intake Kit (Polished, Part Number 837-122P) for 2004-2008 Acura TSX 2.4L features 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 keep intake air temperatures as low as possible. It can be converted into 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 powerful 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 improving throttle response. The included installation manual contains clear photos and instructions to guide the installer through the entire process. This kit does not require tuning and will not trigger a CEL light. No modifications are necessary during installation. The HPS lightweight mandrel-bent aluminum alloy tubing replaces the restrictive stock airbox, optimizing airflow with superior heat dissipation and long-term durability.

Before You Order
〇 About Import Consumption Tax
At 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
Since our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. 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 products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our homepage, it does not necessarily mean they will fit Japanese model vehicles 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 automatically calculated 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 ample time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. All products are transported via air freight. They are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically 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 the Japanese inspection system. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect 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 only provide returns, refunds, or replacement exchanges if notified within 7 days of receipt for products with shipping damage, defects, or incorrect items. Please note that for products sold through us, warranty-related support will only be provided "exclusively through us." We do not provide support through other companies or distributors located within Japan.
