Many US manufacturers still source generic 20b exhaust manifolds from low‑priced suppliers. The hidden expenses quickly outweigh the initial savings:
- 30% higher warranty claims due to premature cracks and warpage.
- Up to 15% loss in engine efficiency because of sub‑optimal flow design.
- Long lead times (45‑60 days) that stall production schedules.
- Regulatory non‑compliance (EPA, CARB) leading to costly redesigns.
Imagine a 5‑year fleet where each vehicle loses 3 % fuel efficiency—your bottom line could drop by millions.
