89 CRX DX....I just got headers and a highflow cat. What oxygen sensor should I go with? Bosch or NTK?

 

get the universal and wire it yourself its only one wire and its all the same... well thats my opinion... its also a difference of 17 to 32 dollars and i think at autozone the universal is a bosch

 

i bought the universal one too, i beleive it is a bosch, and was under 20 chux

 

Either is fine, but I'd rather an NGK over a Bosch myself.

 

Want a real Honda one? I have a used spare from my Si that you can buy (e-mail if interested). It fits every header that I know of-the only thing you have to do with the sensor is extend the wire from the it to the original connector (cable should be with header if DC). Otherwise, it is up to you-many threads cover this subject-but the OEM one is going to last the longest.

 

That's what I was thinking...

 

The last time I priced an OEM O2 sensor from Manchester Honda (for a 1st-gen CRX) it cost 178USD. The Bosch ran me $20. There's no way an OEM is going to last 9 times than a Bosch universal.

Here are some tips on R&R. Take some cutting pliers and destroy the body of the sensor such that what's left is short enough to fit inside a deep well 7/8" socket. Some replacement sensors are short enough to fit in the same socket, some aren't. I would suggest trying very hard to source a short one. You can tuck the wire up into the socket and install it that way. If you decide to use anti-seize compound on the threads of the new sensor be certain to keep the sensor tip itself dry. You will ruin the sensor if you don't. -scott

 

dude wtf are u talking about, if you have trouble getting it out heat it up with a torch ,get a set of vice grips and a hammer and go to it.if it still sticks go get a large screw driver/pry bar and break that fu(ker .all it is,is porclyn"sp" its real easy.and yes then put some lube and put the new one in.
