Suitable for Cadillac CTS.
Thermalnator is a unique high-temperature shielding gasket that replaces the stock intake manifold gasket. The cooling properties of Thermalnator reduce heat by stopping metal-to-metal contact between the intake manifold and the engine block. Using a Thermalnator gasket reduces the heat of the air entering the engine, resulting in a power increase of up to 5%. The Thermalnator gasket allows the intake manifold to function like an intercooler. Because the manifold is no longer being heated by the cylinder head, heat from the incoming air is dissipated through the aluminum very rapidly. The basic formula is that for every 5°F increase in intake air temperature, air density decreases by 1%. Higher air density results in more horsepower.
Average testing shows a 25-degree Fahrenheit drop, with up to a 35-degree drop seen in some applications. This is why the Thermalnator gasket is an excellent upgrade for stock or modified vehicles.
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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will look into it 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 using the tabs on our top page, it does not necessarily mean 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 before ordering if you have any questions.
○ 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, the actual shipping cost may occasionally differ significantly from the automatically calculated amount. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow 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 not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are essentially 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 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 arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that 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. Furthermore, for products sold through us, 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.
