which oxygen extenders do i need to buy for my long tube headers. 24" and 12", or both 24"? I've had my headers for a while and have been using custom made ones. now i want the real ones.

I've done the obd1 conversion and only have the 1 set of sensors now.

I'll probably get them from thunder racing

which ones?

125-109007 Oxygen Sensor Extension, 24" Square 4-Pin (Rear Sensor on 1995-1997 dual cat LT1 F-body, Front & Rear on 1998-2002 LS1 F-Body) $25.00 Buy Wish


125-109006 Oxygen Sensor Extension, 12" Square 4-Pin (Rear Sensor on 1995-1997 dual cat LT1 F-body, Front & Rear on 1998-2002 LS1 F-Body)

ps. where should i get my new 02 sensors? its $102 for them from gmpartsdirect

 

Id like to know this too. I got under my car the other day and kind of eyeballed it and it looks like 12" will work for the passenger side but the drivers side looks like it needs a 24" extension.

And you will need the flat extensions instead of the square ones. The flat connectors are for the front 02 sensors, the square connectors are for the rear 02 sensors, which you dont have anymore.

As for the actual 02 sensors. I just ordered a couple AC delco's from Dal Slabaugh. They were about $80 for both. Here is how to contact him.

i pulled both of my 02's out and my pass side i had lengthened a lot but my drivers side doesnt look like it was touched at all, it has about a 6" wire to it. or maybe i already bought one extender for the drivers side. its been so long i cant remember.

thanks for the help,

 

check out speedincom on ebay he has them for $16.50 plus $8.50 for shipping and he will combine ship the items. i got mine from him and i think they were 12" plenty long enough. i had to fold them over and zip tie them. just dont forget to mention the year and make of your car.

 

I had a pair of 24 inch extensions on both sides, they were actually pretty long and had alot of extra slack so I ended up picking up the 12 inch extensions instead and swapped them.

 

its been so long since ive worked on my car, i actually already had them, and forgot about them. but one wire on the end of mine came out of the plug. ill have to have it fixed.

 

I have the 24" extensions, and they do seem a bit too long but zip ties make it tidy under there.
