Built for performance and show, the HPS Blue Cold Air Intake Kit for the 2006-2011 Honda Civic Si 2.0L relocates the HPS Performance air filter outside the engine bay to deliver the coldest possible inlet temperatures. Compared to conventional short ram air intakes, the HPS long ram cold air intake provides cooler, more oxygen-dense air to cause a more powerful explosion within the vehicle's combustion chamber, delivering dyno-proven performance gains of +8.9 Whp horsepower, +7.1 ft/lb torque, and improved throttle response. The included installation manual provides clear photos and instructions to guide the installer through the process. An HPS silicone coolant reroute hose is included to prevent the intake pipe from rubbing against the stock coolant hose. The kit also includes an air straightener to minimize the possibility of a CEL light; while the kit does not require tuning or modifications, the front bumper must be removed for installation. HPS lightweight mandrel-bent aluminum alloy tubing replaces the restrictive stock airbox, optimizing airflow with superior heat dissipation and long-lasting durability. The HPS cold air intake system features HPS signature race-proven reinforced silicone hoses and industrial-grade 100% stainless steel T-bolt clamps, ensuring reliability under the most demanding driving conditions. The all-new HPS Performance air filter is manufactured in the USA and designed with performance in mind, providing superior filtration without sacrificing airflow. It is washable and reusable. Not CARB compliant. Vehicle Application: 2006-2011 Honda Civic Si 2.0L.
Before You Order
〇Regarding Import Consumption Tax
At the Shafutoya 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Compatibility Check
Our entire product database is based on North American (USDM) vehicles; please confirm compatibility with Japanese (JDM) vehicles 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 investigate for you.)
If you place an 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 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 Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually by email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection standards," and we are unable to provide documents such as strength calculation reports for Japanese vehicle inspection purposes. Therefore, all parts are sold for 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 replacement products if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or items different from what was ordered. Furthermore, regarding products sold through us, we will provide warranty support "exclusively through our company." Please note that we do not provide support through other companies or distributors located within Japan.
