1. High Unit Price – Imported OEM parts often carry a 30‑40% premium due to limited supply chains.
2. Inconsistent Quality – Non‑certified castings lead to cracks, thermal fatigue, and costly warranty claims.
3. Long Lead Times – Typical 6‑8 week delivery hampers production schedules.
4. Regulatory Uncertainty – US‑specific standards (EPA, CARB, ISO 9001) are frequently overlooked by overseas suppliers.
5. Lack of Customization – One‑size‑fits‑all designs limit engine‑specific performance tuning.
Data point: A 2025 survey of 312 US automotive OEMs reported a 27% increase in warranty costs linked to low‑grade exhaust manifolds.
