Welcome to MJ Select. We are Japanese seller. We ship authentic items from Japan. Please enjoy shopping with peace of mind! -------------------------------------------- 【About Included Manuals】 If a manual is included, it will primarily be in Japanese. We recommend using image translation apps if needed. 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. -------------------------------------------- High compression piston, piston ring, and piston pin are included in 1 SET to be compatible with various car models.
