Features HPS performance race-proven reinforced silicone hoses, industrial-grade 100% stainless steel T-bolt clamps, and a washable/reusable performance air filter.
>The included installation manual provides clear photos and steps to guide the installer through the entire process.
Modification of the stock airbox is required.
The HPS 4-ply reinforced high-temperature blue silicone Shortram Air Intake Kit with HPS Performance Air Filter replaces the 00-03 S2000 AP1 2.0L stock OEM restrictive rubber intake hose with high-temperature reinforced silicone material and replaces the OEM cone filter with a larger HPS performance air filter. The HPS performance silicone shortram air intake kit improves airflow and throttle response, and minimizes heat soak by retaining the stock fresh air scoop and sealed airbox design. The included airflow velocity stack also smooths out airflow and reduces turbulence. The HPS silicone post-MAF air intake tube with HPS performance air filter delivers dyno-proven performance gains—an increase of +4.2 Whp and +3.4 Ft/lbs of torque—without the need for re-tuning. The intake kit also makes the S2K sound louder and more aggressive compared to the stock intake setup. This silicone intake kit does not trigger a check engine light. Installation time is approximately 1.5 to 2 hours. Installing the large HPS filter into the stock airbox requires modification, including trimming the lower air intake box lid and removing the internal snorkel from the upper air intake box. The all-new HPS performance air filter is designed with performance in mind, providing excellent filtration without sacrificing airflow. It is washable and reusable. All HPS performance air filters are made in the USA and come with a HPS 1-year limited warranty. Not CARB compliant. This HPS intake is designed for the 2000-2003 Honda S2000 AP1 2.0L.
Before Ordering
〇Regarding Import Consumption Tax
At the Shaftoya 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Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM). Please check whether the parts can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate it 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 vehicle model on the tabs on our home page, this does not necessarily mean they will fit Japanese market 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.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are not shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for these systems. 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, there may be damage to the shipping box or product. We only provide returns, refunds, or replacements for damaged items, defective products, or items different from what was ordered if we are notified within 7 days of receipt. Please understand this. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located in Japan.
