Fits all variation models including RHD, international models, etc.
Important Notes:
- ECU calibration is not required
- Compatible with all factory-installed intercoolers
Technical Notes:
Our charge pipe upgrade kit utilizes a smooth-flowing, large-diameter cold side to increase airflow and utilizes the factory-diameter hot side outlet to assist with turbocharger spool. 4-ply silicone couplers are used throughout the design for several reasons.
-
Heat Soak Reduction: Silicone hoses have significantly lower heat transfer properties, especially compared to steel or aluminum.
-
Strength and Rigidity: Factory rubber hoses are known to expand, which worsens as boost increases. Over time, the rubber structure weakens, increasing the likelihood of boost leaks. We also managed to melt the factory rubber hoses several times during track adventures in our shop car. Our high-temperature 4-ply silicone handles high turbocharger temperatures much better than stock rubber hoses.
-
Smooth Airflow: Custom-molded silicone allows for higher-flowing bends than metal tubing.
-
Optimal Fitment: We found that factory rubber hoses do not offer the most desirable fitment, especially when paired with aftermarket radiators. Our silicone hoses provide even better fitment than the factory ones.
Kit Contents:
- (2) 4-ply silicone couplers
- (1) 1/8" NPT auxiliary service port
- (4) 304 stainless steel lined clamps
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 other than the total amount paid at checkout.
〇 Confirmation of Fitment
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing your order. (Please feel free to contact us if you are unsure if the listed product fits your vehicle. Our support team will investigate for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they will fit Japanese market models without modification.
All products have been 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 payment. 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 shipping cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic delivery in Japan, international delivery takes about 7 to 14 days, so please order with enough 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 will not be shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they do not conform to the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for such purposes. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," 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 delivery damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding damaged products, defective products, or incorrect items received. Please note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
