Keystone GM1132101 Catalytic Converter Air Injection Tube

The Keystone GM1132101 Catalytic Converter Air Tube is a direct-fit replacement emission control component designed to restore proper function to your vehicle's secondary air injection system. This tube connects the air injection pump to the catalytic converter, delivering fresh oxygen into the exhaust stream to help reduce harmful emissions and maintain optimal catalytic converter performance.

Key Features:

• Direct replacement for GM OEM part number GM1132101
• Designed for vehicles equipped with secondary air injection (AIR) systems
• Helps complete combustion of unburned hydrocarbons before reaching the catalytic converter
• Essential for proper emission control system operation and passing emissions testing
• Engineered to withstand high exhaust temperatures and corrosive conditions
• Restores proper air flow to reduce harmful tailpipe emissions

This air tube is a critical component of the emissions control system, routing fresh air from the secondary air injection pump into the exhaust stream ahead of the catalytic converter. When functioning properly, it helps ensure complete combustion of exhaust gases, reduces toxic emissions, and helps prevent check engine light codes related to the air injection system.
