It Works Like It Should!!!!
I got this oxygen sensor (it actually is an air-fuel ratio sensor) from China through Amazon for around $30, as I do not like to spend $181 for an OEM Denso sensor from Autozone. It looks like a high quality part, with anti-seize compound already applied on its thread. It was a perfect fit. Works like a charm. Highly recoommended.

Works for 2005 es330 b1s1
Worked perfectly for my 2005 Lexus es330 with a heater code. The bank 1 sensor 1 OEM sensor pigtail is a little bit shorter than this one but still works just fine.
