ARP BMW 2.3L (S14) 4cyl Head Stud Kit
Whether you are performing a complete rebuild or standard maintenance, having the right engine components is essential for your vehicle to run 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' broken engines were caused by fastener failure. At the time, there were no commercial studs or bolts available to address this issue. So, drawing on his many years of experience manufacturing fasteners for a major aerospace subcontractor, Holzapfel founded ARP (Automotive Racing Products). In the years that followed, the company grew from what was literally a backyard garage operation into a highly diversified manufacturer with seven entities in Southern California, totaling 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 Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred upon importation on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Confirmation of Fitment
All product databases are based on North American vehicles (USDM). Please confirm whether or not they can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure whether the 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 fitment, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer name, 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.
○ 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 calculated automatically. In such cases, we will contact you individually by email.
Basically, 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 delivery times. Note that all products are transported by air freight; they are never shipped by sea.
○ Regarding Japanese Vehicle Inspection Compatibility
Basically, all products we handle 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. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product. Please understand that we will only handle returns, refunds, or replacements for products with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, we will handle warranty-related matters "only through us." We do not provide support through other companies or distributors located in Japan.
