Will it fit my Fiat 500?

Must be the correct emissions-spec cat for your engine and year, or it'll fail MOT. Type-approved units only.

Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.

Signs your Fiat 500 catalytic converter needs replacing

Fitting it yourself

Bolt-on or welded depending on setup. Lambda sensors often transfer over.
