Fitment:
2022-2025 Subaru WRX
Features:
The Verus Engineering Air Oil Separator (AOS) keeps the intake system oil-free. Oil in the intake system can lower octane ratings, leading to detonation, power loss, and carbon buildup.
Four 5-micron coalescence filters (one each at the inlet and muffler outlet), along with baffles and stainless steel mesh, filter crankcase air with unprecedented precision. Internal baffles built into the AOS itself further enhance filtration performance.
With optional add-ons like the Verus AOS drain-back kit or AOS coolant add-on kit, this AOS can be tailored to meet your specific needs seamlessly.

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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Confirmation
As all product databases are based on North American vehicles (USDM), please verify whether the product can be installed on Japanese domestic vehicles (JDM) 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 investigate it for you.)
If an order is placed 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 homepage, it 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 with any questions before ordering.
○ Regarding Shipping
Shipping fees are paid at the time of checkout. Estimates for shipping fees 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 fee differs significantly from the actual cost. 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 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us to check delivery times in advance. All products are transported via air freight. They are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are fundamentally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for these standards. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and usage are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, packaging and products may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defects, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
