Most U.S. OEMs face three recurring issues with off‑the‑shelf manifolds:
- Excessive Price: Imported units often carry a 20‑30% markup due to middle‑man fees.
- Quality Inconsistencies: Cracks and warping appear after 5,000‑10,000 km of operation, leading to warranty claims.
- Long Lead Times: Typical delivery exceeds 45 days, disrupting production schedules.
According to a 2025 industry survey, 62% of purchasing managers reported “delayed engine testing” caused by late manifold shipments.
