OE Style Construction

Denso’s OE Style product line is built around exact replacement fitment and consistent sensor performance. This oxygen sensor uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and long service life in demanding exhaust environments. If you need a Denso oxygen sensor 234-4641 for Mitsubishi Eclipse, Mirage, Diamante, or Galant applications, this OE-style design is intended to match the original sensor layout and connection style.

This part cross-references Bosch 13417 and NTK 21511 for the same application.

What It Helps Address

  • Check engine light caused by oxygen sensor fault codes
  • Incorrect air-fuel mixture readings from a worn sensor
  • Reduced fuel economy from slow or inaccurate exhaust feedback
  • Rough idle or drivability issues tied to sensor response
  • Failed emissions testing related to oxygen sensor performance
