Perrin Performance 3" Reinforced Silicone Inlet Hose
The PERRIN Performance 3" Turbo Inlet Hose is specifically designed for turbocharger upgrades that feature a 3" inlet. PERRIN Performance is the only option that does not require building a custom intake system, as it is compatible with any replacement intake system that works with the OEM inlet hose.
The inside of the PERRIN inlet hose is completely smooth and has a significantly larger inner diameter than the OEM part. Eliminating the pleats found in the OEM hose increases airflow, improves horsepower, reduces turbo spool time, and enhances acceleration. The PERRIN inlet hose is reinforced with a stainless steel support wire embedded within the layers of silicone. This support increases the rigidity of the hose and prevents collapse when used in large turbo applications with restrictive filter elements or extreme boost levels.
The PERRIN inlet hose features a machined aluminum insert bonded into the silicone layers, ensuring a secure connection to the blow-off valve hose and making installation even easier. All spigots on the PERRIN inlet hose have a 1/2" inner diameter to maximize flow from the crankcase vent and other vacuum connections. All connectors used in our hose are glass-reinforced nylon (rated to 400°F), capable of withstanding engine bay temperatures from normal driving to extreme racing conditions.

Before Ordering
〇 Regarding Import Consumption Tax
At 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.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing an order. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check for you.)
If you 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 model from the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products are translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of settlement. Shipping estimates are calculated automatically when 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 cost and 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 about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are fundamentally designed and manufactured outside of Japan. Please be aware that they are not compliant with "Japanese Vehicle Inspection (Shaken) standards," and we cannot provide documents such as strength calculation reports for Japanese inspection purposes. 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 box or the product itself. We will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through our company, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
