purchased.....

Just got mine! They look and are boxed identical to the set of SSAC's I got for Shawn's car not too long ago. Only difference I see is that there is no plate welded to the front header assembly like on the SSAC's. I'll add info as I attempt to install them tonight.

dunno if this has been asked but im not reading all 7 pages to find out. where would the o2 sensors be relocated to? i didnt see holes for either one. for sure didnt see one for the rear sensor.
02-05-2010
In the rear header. You still need to extend the stock o2 sensor harness
02-05-2010
Should you buy an extension or extend it yourself? I've heard of people soldering in new wires, I've also heard that can mess up the readings from the sensor.Originally Posted by bluegtp91

in my opinion i would rather let someone else deal with wiring but you can do either
02-05-2010
it wont mess up the readings from the sensor. if you can solder save yourself $20 on a harness that is just wire and two connectors.

Got 'em installed last night!
It took me 5 hours, but it's done. One of the more difficult things I encountered was snaking the rear header into place. I ended up pulling the trans dipstick and rocking the engine as far forward as possible. They seal great with the step-down band clamps like what ZZP sells. I used the horseshoe clamps underneath, and they leak a bit, but that will be welded soon anyway. And, just because they are slip-fit headers doesn't mean that they are easy to line all three pieces up. It took a bit of work, but they fit and work great. Identical to the SSAC in the way they fit. I'm almost 100% certain they are the same thing without the badge.

Thanks to you.... we can now all condone buying these since we know for sure they fit.

Glad I could be of service to the community.
And, thank you, Blue for starting this thread.

Regarding the O2 sensor "issue" discussed above. Did you have to extend the wiring??? and if so, how did you go about that?? and if you didn't have to....awsome!! haha
02-05-2010
Extending the wiring on the sensor itself can mess with the reading. As long as you extend the harness, you're fine.
02-05-2010
How is splicing in more wire different in the resistance that it adds compared to a harness that does the exact same thing but with clip in connectors?
02-05-2010
it isnt unless you do something stupid like changing the wire gauge considerably or adding like a mile of more wire. if you do either of those then youre already dumb.
02-05-2010
Just raising a point.
02-05-2010
It's not about resistance, it's about the sensor getting a reference sample through the standard wires. Screwing with these wires can screw up that sample, which can screw up your reading.
02-05-2010
So the sensor reads through the wires it sends the signal through?
O2 sensors send a signal. This signal is changed by its changed output voltage. That means only added resistance can change the voltage.
02-05-2010
It actually gets a sample of air though the wires, though. I know it sounds strange, but O2 sensors generate a voltage from the differential of O2 content, so it has to have both.
02-05-2010
So extending all of the wires equally which is the same as using the harness, is not the same because the O2 sensor generates the voltage through the difference of O2 levels.
Do you see my point here? What if you extended the wires BEFORE the factory connector.
The wires have to be extended, so no matter where you do it... it'll still be longer.
I realize it compares, but it doesn't do it through the wires that connect to the PCM...
