Tenía tiempo con el código del sensor de oxigeno del banco 1 activo. Vi la pieza en Amazon en varias marcas y escogí la marca denso por no ser tan mala. Ya tengo un mes que lo instale y se notó mucho el cambio en el rendimiento del carro. Mi vehículo es un pontiac Grand am 2001 3.4

Worked as advertised. Easy to install. It's only been a couple of months (sept 2019), so the jury is still out on product performance. Will update.
