Technical Accuracy & Serial Number Verification

Cummins engines are often configured differently depending on country regulations, emission standards, or end-customer requirements. Bespoke builds are common in power generation and marine applications.

For accurate pricing and correct part selection, we recommend providing:

• Engine Serial Number (ESN)
• Current part number (if available)
• Application type (Generator / Marine / CHP)

This ensures precise supply and eliminates compatibility risk.

AMS Parts only supplies genuine or OEM Cummins parts. We do not offer aftermarket components. Our focus is quality, traceability, and ensuring long-term engine reliability for our clients across the UK.
