Why Your Operations Lose Money Without the Right Manifold
- High Price, Low ROI: Generic imports can cost up to 30% more per unit.
- Premature Failure: Inferior cast iron leads to cracks, causing downtime and warranty claims.
- Sub‑optimal Exhaust Flow: Poor design reduces horsepower by 5‑8% and raises fuel consumption.
- Long Lead Times: Overseas suppliers often need 6‑8 weeks, delaying production schedules.
- Regulatory Non‑compliance: Missing CE, ISO or RoHS certifications can halt shipments.
