Get Free Quote in 24 hWhy Purchasing Managers Struggle with Diesel Exhaust Manifolds
High price & low quality are the two most cited complaints in recent B2B surveys (2025 Global Diesel Parts Report). Below are the three pain points you probably face:
- 🔧 Excessive warranty claims – up to 28% of shipments return for cracks or warping.
- 💰 Inflated unit cost – imported cast‑iron manifolds from secondary suppliers can be 35% higher than OEM‑grade.
- ⏱️ Long lead‑times – 6‑8 weeks delay jeopardizes production schedules and OEM certifications.
These issues directly erode ROI, increase downtime, and threaten compliance with EPA and Euro 6 emission standards.
