I just purchased a set of 1999 Hooker Super Comp. Long Tube Headers and was un-sure of what type of 02 sensors to use on the back of the headers, any help with this would be greatly appreciated, my car is a 1999 Z-28 A-4, thanks.

Your stock ones

 

I just did the same thing on my 98 z28 and I used the stock ones. Its the rear o2's im not sure what to do with. i have O2 sims in their now. but if you're planning on doing ignition modifications soon and other mods I have read and heard that wide band O2's are a better way to go.
