I just bought PPE header. It came with the conditioner. My friend said that it will work without the conditioner and he installed the header without it. Will it affect the performance?

When I was looking at the instruction, it looks really complicated

 

The conditioner is there to fool the second o2 sensors into believing that the cats are still there so you don't get a CEL. I don't know what your friend did, but if you don't have a CEL, you're OK.

get something like this if you are worried... i had it on my 03 Sentra Spec V running straight pipe, no CEL at all...

 

Thanks for the input

 

Yeah, I looked at the PPE instructions for the conditioner and immediately went onto ebay and picked up some tig-welded off-road rated CEL eliminators. Good quality pieces, and should have the same effect as the electronic box without the wiring headaches.

 

I didn't know that they came up with a solution for the CEL !

We are in 2015 babe lol

 

I installed the O2 spacers from ebay and every now and then the CEL comes on and after a few miles it goes away on its on.. Maybe i need better spacers..

 

I just got my PPE headers installed.

Without the o2 simulator (the black box thing that splices into the ecu/pcm wiring), the check engine light (CEL) came on after about 10 - 12 miles.
I cleared it twice without installing the box and yup, both times it came back.

Been a good 200+ miles now without any CEL after the o2 simulator box was installed.

 

Best way to go with the simulator. When i first installed mine without it just with the o2 bug it was good just for the summer. When winter time hit and it got really cold out the CEL stayed on and never went off. Installed the o2 simulator and not one CEL even in 5 degree weather.

 

Did you install the headers with any O2 sims that screw into the existing O2 bungs or just the O2 sensors straight-up?

 

Just the o2 sensors themselves with the wire extensions (provided in the PPE install kit).

 

^Ok. Well that should make sense. I'd be a little worried if you ran CEL eliminators pictured above in this thread AND then got the same CELs. I've got the coated PPE headers and CEL eliminators ready to be installed as soon as I have a garage to do the install in. LOL!
