Citroen C4L 1.8 Branch Pipe Three-Way Catalytic Converter – Restore Peak Performance & Ensure Emissions Compliance
This premium catalytic converter is designed specifically for Citroen C4L 1.8L gasoline engines (2000–2025). Engineered with a high-grade ceramic honeycomb substrate and durable steel shell, it ensures maximum purification efficiency, optimized performance, and extended service life. Whether you’re facing a failed emissions test, a persistent check engine light (P0420), or reduced fuel economy, this direct-fit replacement restores your vehicle to factory standards.
Efficient Emission Purification
Premium ceramic honeycomb substrate loaded with precious metals (Pt, Pd, Rh) achieves over 90% purification efficiency, converting CO, HC, and NOx into harmless gases.
Durable & Heat-Resistant
Built with a robust 409L stainless steel shell and precision internal structure, capable of withstanding 600–800°C exhaust conditions and long-term vibrations.
Performance Recovery
Minimized exhaust backpressure restores lost horsepower, fuel economy, and smooth engine operation.
Direct-Fit Installation
Designed to match Citroen C4L 1.8 factory mounting points – no welding or modifications required.
Certified Quality
Manufactured under ISO9001 standards with strict factory testing for reliability.
