So I order NTK o2 sensor from Rock Auto thinking I am ordering the front sensor for a two sensor system. One upstream and one downstream. Well I ordered the rear one by mistake. So I put it in. Found a Denso local for the front, try to put it in, only to find out the pig tail is to short. Does anyone know if the NTK left upstream o2 sensor pig tail is 17"? Before I order it from Rock Auto. They can't tell me until Monday. The engine is a 360 5.9 non California emission. Stock. Thanks

 

Doesn't Rock Auto also have the Denso unit? Compare the part # on Rock Auto.

 

They do. The part number for the denso matches the part number for the denso unit I got local. The pigtail is only 12.89 inches. I need at least 17". The bosch I took out was 17" and reached fine. I want to go with NTK, but Rock Auto can't tell me what length the NTK is. And there are no specs on Rock Auto.

 

It's 18 inches and I think you want an NTK 23014 .

 

23014 is the down stream on my truck. 23056 is left front upstream. Where did you find the 18" spec? Thanks again.

 

The sensor itself is the same, but here you go. http://www.ngksparkplugs.com/part_finder/index.asp
