I bought them from a honda parts place online

Awesome DIY. Just one question, as I haven't gotten my alpha yet but assume no instructions will come with it, what are the torque specs on the header bolts?

And is the secondary O2 bung further back making it better for an O2 reading form all 4 cylinders?

I would have to look up the specs because I dont remember, I am running my air/fuel gauge in that bung.

That makes sense! I'll probably put my factory O2 sensor there until I get a wideband and then I'll switch them around. I'm guessing you see very similar results between your wideband in the secondary bung and your factory O2 sensor (through flashpro)?

And I'll take a look and find the torque specs, I'm sure they are around.

The stock senors was alittle off from the AEM one but I guess some people have seen it be way off from the aftermarket one.

I just got my Alpha header, looks like the location of the "primary" makes it rather useless for me. So I'll weld on another bung close to the existing "secondary" so that I can read the same exhaust stream with them both. Better to do it now before I install it, otherwise I'd have to take it off again to weld it on.

But I see you aren't using the defouler that came with the header, my understanding was that it just tricks the secondary into thinking that the Cat is still there right? It's best to just install the A/F sensor without it correct?

Thanks!

So I am running the flash pro and I have the secondary o2 sendor disabled. There is no need to use the defouler on the air/fule gauge sensor.

Yeah the defouler keeps the sensor out of the full stream of the exhaust to keep a cel from showing up. If you don't have a flash pro then you do need to use it on the stock o2 sensor.

good right up. always wondered how this was gonna be done. dont have an 8th gen yet but it was just weird to me with the motor sitting backwards

Thanks........

i was gonna ask if you were throwing a cel with the defouler but your using flashpro.....soo nvm. if anyone has this header and not running fp, is your cel light on with the defouler, cause mine is

[obert]

Witch one do you have it on ?

[Pentabubs]

so i don't need power tools for any of this install, correct?

as for injecting my stock motor mounts also, those DO need to be re-torqued with air tools??? My friend has an air compressor w/ power tools that ive done lots of other car stuff with, but we apparently can no longer use his garage... so im wondering if i can get away with doing all of this with just basic tools

everythings where it should be. defouler is on secondary bung, primary o2 extended to defouler and secondary o2 to primary bung. reset my ecu after i added the header than 100 miles the cel popped up

Your primary should not be plugged in too the defouler,the defouler should be plugged in too your secondary O2 sensor.

Yeah you can do this install with just hand tools, no power tools needed.

I would try to switch the o2 sendors around and reset everything and see if the works. What ever you do just leave the defouler in that secondary bung. Let us know if switching them works. I am running the flash pro so I don't even have my secondary hooked up at all and the primary is in the primary bung and my air fuel gauge sensor is in the secondary bung. (I really hate this part of the header, this is were people disagree on here the o2 sensors should go)

As far as I have read the way he has it set up right now is how it should be done. I was told never to put the defouler in the primary bung hole. The way he has it now and what you are telling him he would have to put the defouler in the primary bung hole. That is why I told him he should try to switch the o2 sendors back and leave the defouler were it is.

[Will06SI]

His defouler is in the secondary bung where the extended primary belongs..

"defouler is on secondary bung, primary o2 extended to defouler"

Yes thats why i told him to switch the o2 sendors back and try that.

You figure with the countless threads on this he would have got it right the 1st time..

Yeah this is the worst part of installing this hader and now the Alpha header. Skunk2 says one way and then other people say the other way. Some people have no problem with having the header hooked up like skunk2 says and then people do.

It should be one way and one way only !

[Will06SI]

I know its ridiculous at this point i am waiting on the mentioned O2 extension to be made then ordering a new O2 sensor and hopefully i never have to talk about this topic again.
