Best brand o2 sensor to get ? Ngk , Bosch , etc ?

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 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

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.

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.

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.
