90 Degree o2 sensor spacers for 3.0

[SJorge3442]

Hey guys. I'm fighting some lean codes on my 3.0 and need to get my car inspected by EOM and I'm looking to make sure it passes first time.

I'm throwing two leans codes currently, but before it was throwing o2 sensor codes. I wanna install o2 sensor spacers, but I wanna do the 90 Degree ones. My question is, which ones will fit on the 3.0? Space is super tight tight in our sensor area.

Are you sure installing O2 spacers will get rid of your issues? What are the lean codes?

The stock O2 sensor also have limited length wiring, I imagine it will be difficult to get them to work with a 90deg-angle spacer

Spacers will only stop cat codes, and are only for the rear sensors. They won't fix lean codes or bad sensor codes.

I understand that, I just think the lean codes are trumping the cat codes right now. I feel once I fix the lean code, the cat codes will be back. Does that make sense?

Yeah. I'm not sure which 90°spacers would work, but it is definitely tight in there. I would say the less space it needs, the better.

You don't need 90s there is enough room to just use the straight spark plug non fouler even enough room to double stack them, but I wouldn't recommend it on the 3.0 the system is way to sensitive and they don't work. You will still end up with cat efficiency codes as well as 02 sensor slow to respond.

People have had luck using spacers plus stuffing some steel wool on the spacer. I know I need to replace the o2 sensors but I'm on the fence of a jhm tune, so I keep putting them off since the tune makes the sensors obsolete
