NO LONG LIFE
Wished they lasted longer than they do on my 01 suburban but these are not expensive and somewhat easy to install if ramps available. Large crescent wrench needed and be sure to apply thread lock included.

New Is Always Better Than Old
I haven't installed them yet, but Denso is a well known Chevy user brand. So it's gotta be good...

Original equipment
Purchased these on advice from auto mechanic after six months of engine code faults for O2 sensors fault. Previously replaced individual sensors of other manufacturers with limited or short success. Purchased all 4 from another company, caused my catalytic converters too go bad! Cost $1000.00 to replace. Still had O2 sensor faults, mechanic suggested I get new ones under warranty. I ordered 4 new Bosch brand sensors, installed and still had fault after reset. Mechanic stated Denso brand was the manufacturers suggested brand. Installed all 4 new Denso sensors and problems solved so far. I suggest you only buy Denso! What a nightmare thinking that other brands were of high quality and correct for my vehicle as there description stated. Only installed Bosch for a couple of days while diagnostic testing, faults keep coming back after reset. Sent back for refund after new Denso were installed and resolved issue immediately. Costly mistake using other brands for short period while looking for other issues, like broken wires,computer, replacement with no positive results. Totally destroyed converters, chunks of catalyst material blowing out tailpipe. What an expensive lesson learned 😪!

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.
