This Denso wideband air/fuel sensor is the correct replacement for the 2002–2004 Acura RSX Type S (DC5), 2002–2005 Civic Si (EP3), and 2002–2004 Honda CR-V. It’s also the primary O2 sensor used as a cost effective solution for Hondata KPro

Be cautious of listings that advertise lower prices and claim to include a Denso box, these may not be genuine Denso sensors. If the sensor isn’t made by Denso, you’re simply paying for the box, not the quality.

This sensor directly replaces Honda/Acura part number 36531-PRB-A01 and installs as a true plug-and-play unit — no cutting or splicing required.
