Built for performance and show, the HPS black cold air intake kit for the 2006–2011 Honda Civic Si 2.0L relocates the HPS performance air filter outside of the engine bay to deliver the coldest possible intake temperatures. Compared to a traditional short-ram air intake, the HPS long-ram cold air intake delivers colder air with higher oxygen content, causing a more intense explosion in the vehicle's combustion chamber, resulting in dyno-proven performance gains of +8.9 Whp horsepower, +7.1 ft/lbs of torque, and improved throttle response. The included installation manual features clear pictures and instructions to guide the installer through the entire 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 chance of a CEL light. While the kit requires no 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 excellent 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 for reliability in the harshest driving conditions. The all-new HPS performance air filter is made in the USA and designed with performance in mind, providing excellent filtration without sacrificing airflow. Washable and reusable. Not CARB compliant. Vehicle Application: 2006–2011 Honda Civic Si 2.0L.
Before You Order
〇 About Import Consumption Tax
At Shafutoya Shopping Site, we cover 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
Our entire product database is based on North American vehicles (USDM). Please check whether the parts can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. 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 using the tabs on our home page, this 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 calculated automatically once 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 amount calculated automatically. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7–14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery dates. Note that all products are transported by air. They are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
In principle, all products handled by our company are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we are unable to provide strength calculation documents or similar paperwork for the Japanese inspection system. 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 package as soon as it arrives. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, warranty-related support will be provided "only through our company." Please note that we do not provide support through other companies or distributors located within Japan.
