Product Details

Denso remanufactured starters are rebuilt with a test-and-replace process that focuses on electrical integrity, current transfer, and bench-tested operation. The reman starter line is based on Denso’s OE experience supplying starter technology to automakers, and this unit is engineered to deliver factory-original starting performance for the Mazda 6. This part number 280-4293 is a direct-fit replacement for 2006, 2007, and 2008 Mazda 6 models listed in the fitment data.

This part cross-references Bosch SR4237X and Remy 16088 for the same application.

What It Helps Address

• Slow or weak engine cranking
• No-start conditions caused by starter failure
• Intermittent starting after key turn
• Electrical resistance at worn terminals or brushes
• Starter noise related to worn internal components

Installation Notes

Verify the vehicle’s 12-volt system, starter rotation, and OE-style mounting before installation. Confirm the application against the Mazda 6 model year and existing starter configuration, then inspect battery condition, cable connections, and charging-system output to avoid repeat starting issues. For 2006-2008 Mazda 6 service, match the replacement starter to the listed 1.4 kW specification and part number 280-4293.

Quality Assurance

Denso reman starters are subjected to high-voltage testing, component replacement, and bench testing to confirm electrical performance before release. The remanufacturing process also reuses serviceable materials, supporting a more resource-conscious repair choice while maintaining OE-style starting function.
