How Honda sources OEM parts
- In-house manufacturing of select components and assemblies at Honda-owned plants, including some engines and major driveline components.
- External suppliers (Tier 1) contracted to design, engineer, and manufacture components to Honda specifications under formal quality agreements.
Who are Honda's OEM suppliers?
- Tier 1 suppliers that deliver complete systems and modules (for example engine control units, braking systems, HVAC, and chassis components) under Honda's specifications.
- Joint ventures and technology partners that co-develop advanced systems such as hybrid powertrains, electric motors, and power electronics.
- Regional and local suppliers to support regional production and reduce logistics costs and lead times.
- Qualification, quality assurance, and logistics partners that support just-in-time delivery and continuous quality improvement.
Notes on OEM vs aftermarket
OEM parts are manufactured to Honda's exact specifications and are typically sold through official Honda channels, dealers, and authorized distributors. Aftermarket parts are produced by third parties and may vary in fit, material quality, and warranty terms. When buying, consumers and fleets should distinguish between Honda-branded OEM parts and third-party alternatives to preserve warranty and performance expectations.
