Instead of buying O2 sensor extensions is there anything wrong with just splicing wire to the sensors, if done correctly? I just have a hard time paying $42 from summit for 2 extensions...it's just wire and plastic.

If you know what you are doing that is fine. Just make sure you do one wire at a time. I think 2 of the wires are brown and you dont want to mix up the wires.

 

Well, I just figure same gauge wire, soldier, and heat shrink. Anything I missed?

I crimped mine cuz my soldering iron sucks. But yeah soldering would be better.

 

Also use the same kind of wire. Don't make them to long because ur going to change the resistance and us solder

 

If you are going to modify your own, I would definitely try to solder them if possible and then put some heat shrink tubing over the splice.

 

I payed about $30 for my 12'' o2 extensions at http://www.redlineperformanceenginee...om/lt1main.htm and definatly think it will be worth the money. And its just a little insurance from doing it yourself incase somthing isnt the same with the wireing you would be doing yourself.

 

If your skilled enough to splice, soldier, and heat shrink... then there is absolutely nothing wrong with it. Just dont do what I did. I did all that and didnt actually measure how much I needed first. Long story short I later installed the headers and went to plug em in and I still ended up 1/2" short

 

I extended my last O2 harness when I had SLP headers, but with the new long tubes I bought a pair of extensions. There's nothing wrong with doing it yourself and saving a few bucks.

 

Yeah, same here, I got a pair from www.ls1speed.com for around 30 bucks. Peace of mind and the ease of just plugging them in made up for the small cost.

 

Yeah, I don't exactly know how long I will need. I am switching to LT's with the O2 bung in the collector. I figured I'd do 24" just to be safe...
I just have a REAL hard time paying that much money for a couple pieces of plastic and wire. If they were worth it, that'd be different...but cost on those can't be over $20 per pair.

I originally had the 24" extensions to be safe and they ended up being excessively long, so I took them back and got a pair of 12" and they worked fine.

 

Yeah go with www.ls1speed.com extension. They work perfect but like has been said.. go with the 12" and next length down or youll have them hanging everywhere. I have Hooker LTs and I wish I had gone the size under 12".

 

I gotta belive the total cost on a set of extensions is under $5....

 

I spliced wire into the O2 sensors themselves, I was not going to hack into the harness.
I crimped them just to see if it would work and I have had no problems since I did it, about 26k ago.
I watched the O2 counts on my scanner and they look the same before and after.
