Detailed Description

Denso part number 280-4137 is a remanufactured starter in the Mitsubishi OE family, built for Mazda vehicles that require a 12V clockwise starter with 1.0 kW output. It is a practical replacement for drivers needing reliable engine cranking on a Mazda Miata or Mazda Protege, especially when the original starter shows wear from age or repeated starts. This starter cross-references Bosch SR4216X for the same application.

Each unit is remanufactured with attention to electrical integrity and mechanical wear points. Denso replaces key service parts, tests the armature and field coils at high voltage, and verifies performance before release. The result is a starter designed to restore consistent starting behavior while supporting responsible reuse of core materials.

What This Starter Helps Solve

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

Installation Notes and Tips

Confirm the vehicle’s starter specification before installation, including 12-volt system requirements, clockwise rotation, and 1.0 kW rating. This part fits 1999-2005 Mazda Miata, N/A, and fits 1995-1999 Mazda Protege, N/A. Compare the original unit’s mounting and electrical connections to verify match before removal. Clean battery terminals and inspect charging-system condition during replacement to help avoid repeat starting issues.

Quality Assurance

Denso remanufactured starters are bench-tested after rebuilding to confirm starting performance. The remanufacturing process includes replacement of wear items such as bearings, brushes, and seals, along with electrical testing of major internal components to support dependable operation.
