Keystone Bumper Cover Retainer

The Keystone Catalytic Converter Air Injection Tube (also called a catalytic converter air tube or secondary air injection pipe) is a replacement part for a vehicle's secondary air injection system. This system sends fresh air into the exhaust stream, which helps the catalytic converter reach operating temperature quickly and lowers cold-start emissions.

Key Features:

• Replacement air injection tube that carries air from the secondary air system to the exhaust or catalytic converter area
• Made as a direct-replacement, OEM-style part to restore original function
• Helps the emissions system work as designed
• Sold under the Keystone brand, which is known for collision and replacement auto parts
• Available under individual part numbers to match different applications

Replacing a damaged, corroded, or leaking air injection tube helps restore proper secondary air flow. Choose the individual part number that matches your application.
