Oxygen Sensor - Compatible with 1996 - 1999 GMC K1500 1997 1998

I have ordered twice from PartsGeek and have had no problems. The part was exactly correct for my 1998 Silverado and the instructions with the part were accurate and helpful. The part arrived in a reasonable time, however, I do think the $8.95 is too high for shipping such a small package. Nevertheless I do recommend Parts Geek if you need the RIGHT part for you vehicle.

Fast 3 day west cost delivery of Order,product pricing was lowest I could find , thought I would try the premium Nippon Den-so brand as product features offer extended reliable service, includes anti seize compound , was easy to replace , I got lucky old unit was not tight or corroded in place,comes with factory style plug , I did add extra protection using some good quality electrical tape and zip-tie to secure & seal the protective sleeve up at the connector base , and made sure wires were not rubbing or touching any sharp or hot surfaces. Solid looking product and is thus for working great,no more service engine light after I cleared the codes and driving for a few days . saved a bunch of $$$ by replacing my self.

The Denso Oxygen Sensor - Downstream I purchased for my 1998 GMC Yukon was an exact match to the dealership with out the high price tag. I would definitely order replacement parts for my vehicle from PartsGeek again.

Ordered a set of 4 o2 sensors for my 1999 k2500 suburban from parts geek, hence they had best deal around, parts came in quick, direct fit, no issues, check engine light is off now. Definitely will be looking for parts on here as I need em. Thanks!

This is a great product for a great price. Was very easy to install without any problems and complications. Perfect fit first time. Would definitely recommend this product.

Went in easy, fit up perfectly with existing wire harness. Taking out the old one was a pain. Hint: Use an oxy-acetylene torch to heat the pipe around the sensor cherry red and crank on it while still hot... nothing else works!

i just recent purchase some o2 sensorfrom the parts geek and the customer service was great and the produck was belived fast.

I ordered this oxygen sensor for 2000 buick lesabre, came nicely packaged, shipping was fast. All service was great. Will order again.

This was my 1st time buying from Parts Geek! Actually, found them accidentally doing a search for my part on Google. Their detail information & listing gave me the confidence to order from them. I ordered a downstream 02 sensor from Parts Geek Tuesday afternoon about 1:30 pm on January 20, 2015. I received the part in my mail box Monday Jan 26th 10 am. Locally in St.Louis, MO the parts store that had it in stock cost $69, while the store that sold it the cheapest cost $55 but had to order it (2) days. Since I wasn't in a hurry, I decided to use parts geek. $28.63 + $8.95 for shipping=$37.58 If you're not in a hurry or buying multiple parts you can see that "The Geek" can save U a LOT!

I recently replaced all four of the oxygen sensors on my 2001 chevy 1500.. Although I did this My engine light problem was not fixed.. Immediately after I installed these I had the pickup tested again and then my problem went to the same or other sensors. So personally I cannot give a good thumbs up for these products because I am not sure that was my problem to begin with. But thanks parts geek and I really do feel you could give better discount codes especially for people that cant order hundreds of dollars in items at a time....
