Before purchasing parts, it is essential to conduct a proper fault diagnosis to accurately identify the root cause. Faults may not be caused by a single issue; multiple factors can contribute to the problem.

For customers without detailed knowledge of vehicle maintenance, deciding which parts to replace based solely on personal judgment can lead to unexpected troubles or increased costs.

Regarding the installation of parts sold by our store, especially for those who lack experience in vehicle maintenance or feel uncertain about the work, we strongly recommend refraining from self-installation. Instead, please have the parts installed by a trusted repair shop or under the supervision of someone with adequate maintenance knowledge and experience.

Please note that Auto Parts Box Japan cannot take responsibility for any malfunctions or issues that occur during or after installation if the work is done without proper expertise.
