what replacment o2s should i get i want everything to be right for dyno.

 

delphi

 

bosch and delphi are the same right

 

everyone suggests acdelco's. nothing else will read right for our cars for some reason..

i believe delphi is acdelco... ? or am i wrong on this

 

Are bosch a bad idea? I haven't heard this. I will be putting a new one on my driver's side this week, but was going to use Bosch....because it's what is readily available. Do I really need to look for another brand?

 

Ive ran ngk for awhile. Now problems yet

 

Year of car? 93 uses AFS21; 94-95 uses a pair of AFS75, 96-97 uses AFS75 front and AFS97 rears.

 

Bosch and Delphi are not the same... If you want a Delphi, I know that ES10006 is the Delphi equivalent of AFS75. I used a pair on my '94. So far, so good. Not sure of the other Delphi offerings for AFS21 and AFS97.

Wow thats cheap! thanks for the link

 

How hard do they ^ hit you for shipping?

 

I priced a pair delivered to Lansing, and shipping was 10 bucks for UPS Ground. That's not terrible. I thought shipping would be much more considering that the O2's seem pretty reasonably priced.

 

most people say to only use delphi

i used a set of bosch without any problems though

 

I am using Denso and have no problems whatsoever with them

 

X2 im using the Denso's aswell and are both reading perfect and no codes. I got mine from www.rockauto.com i think they were 46/each.

 

Denso's :

$32 ea.

I was running Borg Warners at one point, they did pretty good, until I had to drive through a small flood on a country road one night, that fried them. I think I am running old AC Delcos now, runs pretty good for how old they are. One is throwing a code though. I will be going with Denso's next time. Glad I read this thread.

 

so denso or ac i heard of people using rear corvette o2s due to longer wires. if true anyone know what year and part numbers. i have a 95 z28 with long tubes. i need extensions anyway i dont want to leave anything on the table when i get a dyno tune.

 

Don't use Bosch. I swapped mine out about ever 2 months for a year till the warrenty ran out. Switched to AC Delco 2 years ago and I have never had a problem since.

 

how can i make sure there reading right i made my own extensions that came with my pacesetter headers. is there a cheaper way than spending 175 for new o2s and extensions. no one has heard about using 97 vette rear o2s because there longer.
