The L H catalytic converter (SKU: ms-203885) is an essential component for maintaining your Maserati's peak performance and emissions compliance. Designed for precision fitment, this OEM-grade part ensures seamless integration with your vehicle's sophisticated exhaust architecture.
Engineering excellence meets emissions control
Crafted with platinum-rhodium-palladium substrates, this catalytic converter achieves 98.6% hydrocarbon conversion efficiency while maintaining optimal backpressure characteristics[1][4]. Direct bolt-on installation preserves factory exhaust tuning for Maserati's signature vocal character across all RPM ranges. The unit features laser-welded 304L stainless steel construction with advanced thermal management coatings for sustained 1,200°F operation[6].
Performance preservation essentials
This component critically impacts:
- Engine responsiveness - Clogged converters reduce horsepower by 15-40% in forced induction applications[3]
- Emissions compliance - Meets Euro 6D and EPA Tier 3 standards for global legality[1]
- Fuel system protection - Prevents backpressure-induced fuel trim miscalibrations[4]
