Buy Acura CL Catalytic Converters

A catalytic converter is a key part of your Acura CL's exhaust system. Its main job is to reduce harmful emissions by converting toxic gases from the engine into less harmful substances before they exit the tailpipe. Inside, it contains a honeycomb structure coated with precious metals like platinum, palladium, and rhodium. These metals help in chemical reactions that clean the exhaust gases.

If your Acura CL's catalytic converter isn't working properly, you might notice:

• Check Engine Light: A common sign that something's wrong.
• Poor Acceleration: Sluggish or unresponsive engine performance.
• Rattling Noise: Hearing a rattling sound from under the car, especially when idling, can indicate a broken internal component.
• Sulfur Smell: A smell like rotten eggs from the exhaust suggests the converter isn't processing gases correctly.
• Failed Emissions Test: If your vehicle can't pass an emissions test, the catalytic converter might be the cause. (TSX Club, bobhowardacura.com, edmartinacura.com, Beck Masten South)

These issues can arise from engine problems like misfires or burning oil, which damage the converter over time. (edmartinacura.com)

Replacing a catalytic converter on an Acura CL can be expensive. The average cost ranges from $3,157 to $3,203, with parts making up most of the expense. Labor costs are usually between $98 and $143. However, prices can vary based on your location and the specific model year. (Reddit, RepairPal.com)

If your Acura CL's check engine light comes on, it might be due to these codes:

• P0420: Catalyst System Efficiency Below Threshold (Bank 1).
• P0421: Warm-Up Catalyst Efficiency Below Threshold.
• P0422: Main Catalyst Efficiency Below Threshold. (CarParts, RepairPal.com)

These codes often point to issues with the catalytic converter or oxygen sensors.

When replacing your Acura CL's catalytic converter, you have a few choices: (YouTube)

• Aftermarket Converters: These are often more affordable and can be a good option if you're on a budget.
• California-Approved Converters: If you live in California, you'll need a converter that meets their strict emissions standards.
• Direct-Fit Converters: These are designed to fit your vehicle without modifications, making installation easier. (Mdxers, Amazon, Reddit)

Replacing a catalytic converter involves several steps:

1. Lift the Vehicle: Use a jack to raise the car and secure it with jack stands.
2. Locate the Converter: It's usually found between the exhaust manifold and the muffler.
3. Remove Old Converter: Unbolt the old converter from the exhaust pipes.
4. Install New Converter: Position the new converter and bolt it in place.
5. Reconnect O2 Sensors: Ensure all sensors are properly connected.
6. Lower the Vehicle: Carefully lower the car back to the ground.
7. Test Drive: Start the engine and check for any issues. (RepairPal.com)

If you're not comfortable doing this yourself, it's best to consult a professional mechanic.
