Choosing between OEM and aftermarket parts depends on your priorities: lead time, cost, documentation needs, and the criticality of the component.
OEM parts
OEM parts are manufactured to the original specification and can be preferred when:
- The component is safety‑critical or high‑risk
- Documentation and traceability are required
- Long‑term performance consistency is the main priority
Aftermarket parts
Aftermarket can be a good fit when:
- Time and cost are important
- The component is non‑critical
- Multiple equivalent options exist
Practical checklist before ordering
- Confirm engine model and variant
- Use diagrams and callouts where available
- Double‑check compatibility notes
- Clarify quantity and units
