now im not sure which ones i need. I am getting longtubes with an ORY so I would need the manifold ones right??? I am going to have the rears tuned out when I get my tune from Madwolf.

Yes you need the manifold ones.

Hey Robert95 is that O2 sensor that you showed the one for the manifold?

Robert95z

Not sure what you mean as all O2 sensors are the same on your vehicle. The link i showed you is the one you need.

Remember to run it for an hour or so with the old ones. The crap inside the new headers may mess up the new ones.Then put the new ones in.

You need pre-cat sensors.

All four sensors are not the same. The pre-cat sensors have a different connector than the after-cat sensors. One is flat, one is square, they are not interchangeable.

After-Cat: AFS97 PN 25312196
