Review on ECCPP 13675 15525 O2 Oxygen Sensor - Compatible with Infiniti FX35 FX45 Q45 QX56 M35 M45 G20 G35, Nissan 350Z Frontier - 234-4308 Heated O2 Sensor, Upstream/Downstream 1Pcs by Joe Nieves

Ordered for 03 Maxima. Fits perfectly with the B1S2. Ideal cable length (26 inches). Had to cut open the old O2 sensor to pinch it off with an impact wrench. I also ordered copper anti-seize material and will use it from now on. After gutting 1 precat (the ceramic one) can do an antifouling trick and all is well. For those complaining about gutting pre-cats, take care of it. It controls the smog in the first 5 minutes it takes the car to get up to temperature for the main cat to start working Well prekets, don't gut the main cat.
