I need to get an oxygen sensor for my rebuild, i figured i might as well...

Think ill prolly go with the ngk, although some sites have been misleading about the applications it has ... NGK part# 24006 , sparkplugs.com lists it as not being used in RX7s , while at ngk.com it does (this is where i got the part #)...strange.

whered everyone get their o2 sensor and what brand..

 

Get the cheapest sensor you can ..... it really dosen't mater. It is JUST a single wire o2 sensor.

Might even find a bosch box has an NTK sensor (Which is built by NGK)

I just bought a bosch, but I haven't put it in yet... I think my current o2 sensor has been toast since I bought the vehicle, so it'll be interesting to see the difference a new one makes.

 

i bought a universal bosch for like 17 bucks from Advance Auto. Works fine for me

 

i got the bosch for $14 at autozone

 

took the words out of my mouth!

 

i would go with a bosch i have a new one waiting in the garage for me

 

I bought the bosch, because I asked for an O2 sensor, he ordered it in, and when I got it, it was bosch.

I payed 60$ for mine... 14$ wtf? I got shafted..

 

The NGK isnt any better ? I mean i'll pay the extra $$ for the ngk if its better quality, both of my cars had NGK o2 sensors when taken out... I found one online for $35.00 , found another at rx7.com with oem connector for 40.00$ , to me id rather have the best i can get.....im not too fond of the bosch stuff, i myself would think ngk is better....and that you usually get what you pay for

 

You all got shafted, Olympic sells the Bosch one for $7

Mine are more expensive, now that I have to buy the $32 VW wideband :O

 

No, for the stock O2 sensor it doesn't make a difference. The readout on the single wire is just for the ECU's basic balance of A/F ratio and doesn't need to be extremely accurate. The ECU pretty much only read 3 settings. Rich, Lean, and Stoich. I doesn't really calculate how righ, or how lean.

 

there anything better u can get than stock...like a wideband o2 sensor ? or do u need a bunch of stuff to run a wideband o2 ?

 

Reading is one of those skills you didn't pick up did you?

A wideband O2 sensor is only needed to properly tune the engine.
You do not NEED anything better then a cheap bosche for the stock setup or any other setup that used a closed loop A/F system.

A wideband O2 sensor requires more electronics to work that will cost you nearly $400 new.

So let me say it once more for those in the back.
YOU DO NOT NEED AN EXPENSIVE O2 SENSOR FOR ANYTHING THAT IS NOT A WIDEBAND O2 GUAGE, MONITOR, DATALOGGER. If you're just running stock and do not need to tune an aftermarket ECU then you do not need a wideband system.

 

So there's an NTK (by NGK - says so on the box) and an NGK? Calling around locally the Bosch unit costs ~$60CDN and the NTK can be had for ~$45CDN. I hate you bastards who are getting them for $14US!

 

but for using an safcII or something like that you would want a wideband o2 ? would you be constantly running with wideband o2 or would u switch back to closed loop o2 sensor after tuning with wideband

 

When you run a wideband sensor/controler/display you normally install it in a new bung in the exhaust system.

Leaving the stock sensor untouched.

^That I did not know

 

The more expensive Wideband sensor are more susceptible to heat, which is why you mount them lower on the downpipe, but in front of a Cat (if you have one). If you place it in the stock location it'll burn up and you'll be out $60.
