Perrin Performance Subaru WRX/STI Cold Air Intake System
Increase horsepower and add style under the hood. The PERRIN Cold Air Intake System uses proper MAF alignment and piping size. This is critical for maintaining correct air-fuel ratios and preventing check engine lights that plague competitors.
Our intake is made of precision CNC mandrel-bent aluminum tubing for a consistent, perfect-fitting part. Our MAF sensor bung is CNC machined to ensure the MAF sensor fits and aligns perfectly into the intake. This is vital for proper air-fuel ratios and ECU engine management. The PERRIN intake filter element uses open-cell foam to trap dirt and dust. The washable and reusable PERRIN foam filter element can last for the life of your vehicle. The foam filter element offers superior performance with minimal airflow restriction and incredible dust-holding capacity.
With the PERRIN Cold Air Intake System, your car will sound throaty and deep under throttle, a definite change. You will hear the turbo spooling and hear the blow-off valve every time it opens, even on stock units.

Before Ordering
〇 Regarding Import Taxes
At Shaftoya Shopping Site, we pay for import taxes 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 Check
Our entire product database is based on North American vehicles (USDM). Please confirm whether or not it 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 products are sorted by selecting the year, manufacturer, and vehicle model on the tabs of our top page, it does not necessarily mean that they are compatible with Japanese models without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
〇 Regarding Shipping
Shipping costs are paid at the time of checkout. Estimates for shipping costs are automatically calculated once you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US 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 to check the delivery date in advance. All products are transported via air freight. They are never shipped by sea freight.
〇 Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot 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.
〇 Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside of Japan, the packaging box or the product itself may sustain shipping damage. We will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through us, we will only handle warranty-related matters "exclusively through us." We do not handle support through other companies or distributors located within Japan.
