The Verus Engineering Air-Oil Separator (AOS) keeps your intake system free of oil. Oil in the intake system can lower octane ratings, leading to detonation, power loss, and carbon buildup. This unit installs like an OEM part and requires no tuning or setup changes. The Verus AOS filters both the crankcase vent and the intake filter location in a single unit.
With four 5-micron coalescent filters (one each for the intake and exhaust outlets), baffles, and stainless mesh, it filters crankcase air with performance superior to anything else on the market.
The optional coolant hookup kit flows hot coolant through the AOS to reduce condensation buildup during colder months.
Anodized parts may fade over time due to engine bay heat.

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 will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Confirmation
Our entire product database is based on North American vehicles (USDM). Please confirm whether or not the product can be installed on a Japanese vehicle (JDM) before ordering. (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 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 homepage, it does not necessarily guarantee that 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 if you have any questions before placing your order.
○ 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.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 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 times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are basically all designed and manufactured outside of Japan. Please understand that they do not comply with the "Japanese vehicle inspection 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 land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon receiving the product. Since all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging box or the product. We will only provide returns, refunds, or replacements for products with shipping damage, defective products, or products different from what was ordered if you contact us within 7 days of receipt. Please understand that for products sold through us, we will handle warranty-related matters "exclusively through our company." We do not provide support through other companies or distributors located within Japan.
