I have a 95z with pacesetter LT's. Do I need o2 extensions for both headers?

 

Only one on the passenger side will do.

 

maybe in stock form that will do, i mean untouched wiring harness. But mine has been disconnected and moved so many times. With my Jet hot LT's I did both sides, 24" was a little too much so if you can find 12" that would be ideal. I may have a unique situation but not many cars are left "untouched"

 

The 1996 & 97 LT1s have dual front and rear O2 sensors (in front of the Cats and behind) and requires front extensions on both sides. I'm not sure about your year model as the exhaust is different? Also, if you eliminate the Cat/s, you'll need rear O2 simulator/s, or PCM programming to turn-off that function.

 

He has a 95. (signature and post)

 

So I need one 12" extension on the passenger side? thanks guys.

 

i bought 2 24" extensions for mine and i needed both so im not sure why you would only need one? u dont necessarily need 24" but i think u need 2 extensions at least.

 

My 94 needed two...

 

93-95 cars SHOULD NOT need a driver side extension unless the harness has been moved around and it is not routed correctly.

 

Does this also depend on what o2 sensors we you guys may have bought? I know some o2's wires are longer than others.... I bought Bosch a couple of months ago and they went bad after a week. What should I go with this time?
