Frequently asked questions
- They contain precious metals (platinum, palladium, rhodium). OEM units for some vehicles exceed 2,000 USD in parts alone. Compliant aftermarket converters exist but must meet local emissions regulations — verify before approving a cheap alternative.
- A clogged converter can cause severe power loss and overheat. A failing one mainly causes emissions test failure. Underlying causes (misfires, rich mixture) should be fixed first or the new converter will fail too.
