About Thermalnator Thermal Gaskets
Thermalnator is a unique high-temperature shielding gasket that replaces the stock intake manifold gasket. The cooling properties of the Thermalnator gasket 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 heated by the cylinder head, the heat from the incoming air dissipates through the aluminum very rapidly. The basic rule 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 has shown a 25°F drop, with some applications seeing up to a 35°F reduction. This is why Thermalnator gaskets are an excellent upgrade for both stock and modified vehicles.
Before Placing Your Order
〇Regarding Import Taxes
At Shaftoya Shopping Site, we pay the import consumption tax incurred during import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
As our entire product database is 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 whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the model year, manufacturer, and vehicle model using the tabs on our homepage, 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 Shipping
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, the actual shipping cost may occasionally differ significantly from the amount automatically calculated. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to confirm the delivery time. Please note that all products are transported by air. They will not be shipped by sea.
○Regarding Compliance with Japanese Vehicle Inspections
Basically, all products handled by our company are designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese Vehicle Inspection Standards," and we cannot provide documents such as strength calculation reports for Japanese vehicle inspections. 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 of the product. Since all products are shipped internationally from outside Japan, there may be damage to the shipping box or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, we will provide warranty support "exclusively through our company." We do not provide support through other companies or distributors located within Japan.
