All COBRA products come with a TÜV certificate, parts certificate, or ABE (General Operating Permit) where required. This provides you with the flexibility and security to legally and reliably install your accessories without invalidating your vehicle's operating license. Do you already own a COBRA product but lack the certificate? Purchase a certificate independently of any specific product. Please contact us beforehand to ensure that we have the certificate for your accessory in our records and that it is still valid.
