2. Installation Complexity: Installing a catalytic converter air tube can be a complex process that requires specialized tools and knowledge. If you're not experienced in automotive repair, it may be best to leave the installation to a professional mechanic.

3. Potential for False Positives: Some vehicles may trigger a check engine light even if the catalytic converter air tube is not the actual cause of the issue. In such cases, replacing the tube may not solve the underlying problem.

The decision to buy and install a Walker exhaust SX-4Q0V catalytic converter air tube for a 1985-1989 Plymouth Reliant with a 2.2L or 2.5L engine depends on several factors, including the current condition of the emission system, the vehicle's overall health, and the cost-benefit analysis.
