ARP BMW N12/N14/N16/N18 1.6L 4cyl Head Stud Kit
Whether for a complete rebuild or standard maintenance, having the right engine components is essential for keeping your vehicle running smoothly.
They say that to be successful, you must identify a need and fulfill it. In the early 1970s, racing enthusiast Gary Holzapfel noticed that many of his friends' blown engines were caused by fastener failure. At the time, there were no commercially available studs or bolts that could handle this challenge. So, utilizing his years of experience manufacturing fasteners for a major aerospace subcontractor, Holzapfel founded ARP (Automotive Racing Products). In the years since, the company has grown from what was literally a backyard garage operation into a highly diversified manufacturer with seven entities in Southern California and a total area of over 200,000 square feet. These include forging, heat treating, machining, quality control finishing, and packaging/warehousing facilities in Santa Paula and Ventura, California.
Before You Order
〇 About Import Taxes
At the Shaftoya shopping site, we cover the import consumption tax incurred upon importation, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirming Compatibility
Our entire product database is based on North American specification vehicles (USDM), so please verify whether parts will fit Japanese specification vehicles (JDM) before placing your order. (If you are unsure whether a 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 place an 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 vehicle model in the tabs on our top page, this 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.
○ About Shipping
Shipping costs are paid at the time of checkout. 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 via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping 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 delivery times. Note that all items are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide documents such as strength test certificates for this purpose. 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.
○ About Warranty
Please check the contents of your order as soon as it arrives. As all products are shipped internationally from outside Japan, there may be damage to packaging boxes or the products themselves. Please understand that we only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if notified 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 provide support through other companies or distributors located within Japan.
