Genuine BMW Secondary Air Injection Pressure Hose

The Genuine BMW Secondary Air Injection Pressure Hose is an original equipment replacement part. It carries air between the secondary air pump and the secondary air injection system. This system is also called the smog pump or air injection system. It helps cut cold-start emissions by sending fresh air into the exhaust stream, so the catalytic converter reaches operating temperature faster.

Key Features:

• Made to BMW original equipment specifications for a precise, leak-free connection
• Built from materials designed to handle the heat, pressure and under-hood conditions of the secondary air system
• Helps maintain proper secondary air injection operation and emissions system performance
• Replaces a cracked, brittle, collapsed or leaking secondary air hose
• Available in multiple part numbers within this product line

Replacing a worn secondary air pressure hose with a genuine BMW part helps restore reliable air delivery to the system. It can also help prevent secondary air system fault codes and emissions-related warning lights. Choose the specific part number that matches your application.
