What Do Catalytic Converter Decals Do?

Catalytic converter decals provide critical technical and regulatory reference information for Porsche engines fitted with emission control systems.

Core Functions:
• Display catalytic system type, configuration, and emission data.
• Provide reference for regulatory compliance and inspection.
• Assist with servicing and identification of exhaust system components.
• Enhance authenticity and detailing in engine bay restorations.
• Reproduce the original Porsche label design and placement.

These decals combine form and function — ensuring accurate engine identification and professional presentation for restoration enthusiasts and collectors.

Why Do Catalytic Converter Decals Fail or Degrade?

Over time, exposure to heat, chemicals, and moisture in the engine bay can cause decals to fade, peel, or lose legibility.

Common Causes of Failure Include:
• Heat damage from engine operation and exhaust components.
• Fading or discolouration due to UV exposure.
• Peeling or adhesive breakdown caused by moisture or vibration.
• Solvent or oil contamination during maintenance.
• Age-related cracking or wear.

Once worn or damaged, catalytic converter decals can detract from both the technical accuracy and visual appeal of your Porsche’s engine bay.
