Honda/Acura B-Series VTEC Ultra Race Intake Manifold by Skunk2 Racing
Skunk2 Racing is proud to announce the next generation of high-performance intake manifolds for Honda B16A/B17A and B18C engines or VTEC cylinder heads. The long-awaited Ultra Race Intake Manifold is the culmination of years of research and development, building upon the traditional performance of the Pro Series intake manifold.
Using the latest CFD (Computational Fluid Dynamics) software, Skunk2 Racing created a 3-piece modular design that allows for easy disassembly, porting, and changes to the plenum volume by using a removable plenum and optional plenum spacers. The result is a less restrictive design that produces significantly more torque and power than many of our competitors.

Before You Order
○ 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 will be no additional charges beyond the total amount paid at checkout.
○ Confirming Compatibility
Our entire product database is based on North American (USDM) vehicles, so please confirm whether the product can be installed on a Japanese (JDM) vehicle before placing your order. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Additionally, please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in 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 if you have any questions before placing your order.
○ 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 sometimes 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 US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time when placing 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 Compliance with Japanese Vehicle Inspections
All products we handle are essentially designed and manufactured outside of Japan. Please note that they do not comply 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 shipping damage to the packaging or the product. We will provide returns, refunds, or replacement products only if you contact us within 7 days of receipt regarding products with shipping damage, defects, or items different from what was ordered. Please understand that for products sold through us, all warranty-related matters will be handled "only through us." We do not provide support through other companies or agencies located within Japan.
