Downstream Oxygen Sensor - Compatible with 2001 - 2005 IS300 2002 2003 2004

Sensor fit perfectly no modification needed just remove original and instal new one, I have tried to use other brands on Lexus but there's always something that goes wrong either the part is a generic design and a few mods have to be done or the part is just "cheap" and last a couple of weeks, if you want your Lexus to perform the way it was meant to use Denso brand parts.
