H&S Performance プロモーションコード

Add your desired tuner or exhaust system to your cart, proceed to checkout, and enter saveybm in the coupon field to apply your 5% discount before completing payment.

Check H&S Performance's current promotion terms at checkout, as coupon stacking policies may vary depending on ongoing campaigns or product eligibility.

Review the product pages or contact support@hsperformancetuner.com to confirm whether specific items like clearance merchandise or limited-edition tuners are excluded from the saveybm code.

Verify you've entered saveybm exactly as shown, ensure it's entered only once per order, remove any excluded items from your cart, and refresh the page before resubmitting.

H&S Performance accepts returns within 30 days of purchase; items must be unused and in original packaging. A restocking fee applies—contact support@hsperformancetuner.com for specific details and return instructions.

Orders typically ship within 3 business days of cleared payment. You'll receive a tracking number via email, allowing you to monitor delivery progress through your carrier (FedEx, DHL, USPS, or UPS).

Quality beats quantity. We keep the hero code and, when available, a single backup so shoppers and search crawlers never wade through expired duplicates.

Stackability depends on the brand’s cart rules. When stacking is blocked, we flag it inside the coupon notes.
