2x Evan-Fischer Oxygen Sensor Set For 2003 Infiniti G35 (VQ35DE) – Before Catalytic Converter, Left & Right

If your 2003 Infiniti G35 (or Nissan 350Z/FX35 with the VQ35DE engine) is throwing a code or running rough, these upstream oxygen sensors might be your fix.

This is a set of two—driver left and passenger right—that go before the catalytic converters.

They’re from Evan-Fischer, brand new, with a 4-wire setup and a 20.87-inch wire length, so plenty of slack.

They’re heated and thread in nice and easy (M18-1.5 thread).

Comes with a 1-year unlimited-mileage warranty, so no worries.

These are direct replacement, plug-and-play.

Get your engine breathing right and pass that emissions test.

Ships fast—usually same or next business day!
