Help! O2 Sensor

I'm going to replace the O2 sensor on my truck and can't seem to figure out which one I need. I picked one up at Napa yesterday, and the guy gave me one with Bosch PN 15718. However, AutoZone's online parts finder lists my OEM replacement as 15715. Interestingly enough, Napa's online parts number also lists 15715. Did the guy at Napa give me the wrong sensor?

I hate it when people reply to their own posts, but I am hoping to work on my truck first thing tomorrow. I called Napa back and they insist I need the 15718. Everywhere else (including their online site) says I need a 15715. Does anyone know for sure?

Why not print out all the information from the NAPA site and all the corroborating (I love it when I can understand multi-syllibic words) information from Autozone and other sites, go back and see what the guy at NAPA says now.

Well, I'm sure his insistence is based solely on what his computer says. Plus, my only objective is to get the right part for my truck. I really don't care who is right.

Thank you both for your help. 15715 is the number I have come up with from at least a half a dozen sources. I have also found 15718 listed for the 4.9. I'll take it back and hope someone local has a 15715, or it looks like I won't be doing this tomorrow.

man you guys make things easy

When I went to replace mine, the stealer parts manager Couldn't tell me which one I needed. Had to look at the number on the sensor. When replacing it, I couldn't budge the thing wihtout having the exhaust piping hot. I sprayed it with WD-40, even though most of it just smoked off. Just wear a long shirt and watch your arms and hands.
