I just purchased a new Comptech 92-00 SOHC Header and it did not come with the 30" oxygen sensor extension as stated on the parts list on the Comptech website. I called Comptech and they told me that they package them with every SOHC header and without it, the check engine light will go on and the car will not pass emissions. They told me to call the seller to order one for me and that the oxygen sensor extension costs $65. I going to call the seller and ask him to get one for me.

Now my question is what does the oxygen sensor extension do? I thought that aftermarket headers were straight bolt-ons and thus, the oxygen sensor would plug right in. Do all aftermarket headers require this extension or do only Comptech headers require it? I checked notice that none of the Comptech DOHC headers come with the oxygen sensor extension. So it is only for SOHC engines?

I have a '97 Civic EX.

 

Take a look at where your primary o2 sensor is and where the sensor bung is on the new Header. The header sometimes mounts down underneath while the stock location is near the block. The extension is for the relocation.

 

cut and make the wires longer.

Nah, that ain't happening. Gotta get the extension. I prefer to do things right the first time. Maybe it's because I paid $389 for a $529 header:

The header was shipped in a brown box, not a Comptech box. I called the store and they recieved a bunch of Comptech headers, but none of them come with boxes. They told me to call them back later and they'll see if they can find an extension. The headers are indeed new Comptech headers, but what sucks is that the ad made no mentioning that the headers did not come with the Comptech packaging, thus no oxygen sensor extension or manuals. Now I wonder why the Comptech oxygen sensor extension costs $65. Does anybody know of a place where I can get it for cheaper?

 

You can make your own. Honestly it's only 4 wires. Just get you a couple of plugs and get to work.

EDIT: If your in NC I'll make you one like the other member said.

 

Dude, save the money...cut the wires, solder some extensions in there, and you'll be fine. Hell, you could even use butt connectors and it would work, though I wouldn't recommend it.

I have extended many of the sensor wires on my harness to fit my needs...not a lick of a problem.

Hell, if you're in Atlanta, pay me half of what you'll pay for the packaged "extension" and I'll come do it for you.

 

You can also look into the o2 extensions from DC sports.

They might be cheaper. I.E. 50.

 

the oxygen sensor measures hte oxygen content in exhuast gases it does this to make sure your care is running the right fuel to air ratio...in other words if it is running to rich or to lean. so whatever you choose to do make sure its not to not put a oxygen sensor back on.

 

cut splice and extend, save your money

 

make your own extension and save the money for something else better...

 

I agree with all the above. It's so easy to cut, splice, and solder in and extention. I did this on mine, took me about 10min and cost near nothing..

 

It wouldn't be tough to extend the wires like everyone says.
Having said that...you did pay for this product and it should come complete if that's how it's advertised. It also sounds kind of shady that they would get a whole bunch of product without any packaging...and that they would sell it so cheap. Maybe they're knock offs....or one offs??? something like that. Good luck anyways...have you asked the shop why you don't get anything? Or why they don't even come in a Comptech box?

 

I contacted the seller and he says that he will send me the oxygen sensor extension. Provided I recieve them, it looks like the problem is solved.

I highly doubt they're knock offs since they say Comptech and have a Carb number stamped on it. Comptech is a reputable company, but it's not Mugen, so I don't think any knock-off company would sell their headers as "Comptech style." What are one offs?
