How to Identify Garrett Turbochargers

Ensuring your Garrett turbocharger is authentic is essential for optimal performance and reliability. This comprehensive guide will help you identify genuine Garrett turbos by highlighting key features, packaging details, and part numbers, ensuring you make informed purchase and verification decisions.

Garrett Signature Packaging

As of 2018, every one of our Garrett® turbos features distinctly recognizable packaging, making them easier to authenticate as genuine. We use one, easy-to-identify packaging format globally, with box sizes that are compatible with regional specifications.

Your Turbo Nameplate

A nameplate will vary according to whether it relates to an original equipment turbo installed by the vehicle manufacturer or to a turbo bought through the independent Aftermarket. The nameplate shows a customer or Garrett part number, turbo model and serial number – providing you information that might help you order a replacement turbo.

See photos of nameplate examples of OE turbos and replacement turbos.

· Nameplates may vary according to geographic region, assembly plant and local requirements.
· Details engraved directly onto the nameplate pad or onto a separate nameplate, which is then bonded on top of the original factory nameplate.

· Note: you may see Garrett, Garrett AiResearch, AlliedSignal, Garrett Engine Boosting Systems or Honeywell logos on older turbos.

Typical IAM nameplates: · Do not include OE logo or OE name

· Do include:
– Turbo model
– Country of Origin
– Part number in IAM format
– Serial number

OE Name Plates

Part Numbering

All part numbers have 6 digits, starting either with 4, 7 or 8.
Examples: 466214, 700447, 801040. Variations of that part number have a “-” followed by four numbers and possible suffix letters. This is referred to as “the dash number” and informs the reader how the turbo was supplied:

Some Examples
OEM new turbo 700447-0008 First character of dash number always 0, no suffix
OES new turbo 700447-5008 First character of dash number always 5, no suffix
new turbo 700447-0008S No longer used, but may exist on older turbos
IAM new turbo
