I have a 99 Cherokee sport and wanted to know if there is a certain o2 sensor that I should buy when I replace them or if it doesn't matter what kind they are. Also there are two that need to be replaced, correct? Thanks for any help!

 

I've heard Bosh are crap.

 

Ok thanks

 

I was thinking about either Denso or bosh... But now I'm leaning more towards Denso

 

Oem from the stealer is the only one iwould put in it. My 99 went through 2 of them both bosch. Then I went to the dealer and got one and compared the 2. The aftermarkes' sensor bulb is to long and burns the heating element out. Search and u will find mine and other writeups. Save ur self the hassle.I wouldn't even use the denso unless u could compare it with the oem.

 

Thanks!

 

i got bosh have no issues

 

How long have you had them

 

OEM NTK O2 sensors here, for both off amazon for 60 bucks

 

As martyinco said: NTK (subsidiary of NGK) is the OEM supplier and they are available aftermarket for less that the dealership.

 

Wish I knew that 6 mos ago.

Freegdr...
I think the dealer said it was more prevelant on the Obd II.I haven't had any issues since. Like I said its been close to 6 mos.

 

x2. Rockauto.com has em for pretty cheap

 

I always look for NTK as they are the OEM supplier to Jeep (except for 87-90 where it was Bosch and they will work fine for those applications).

 

What model ntk o2 sensor? There are like 5 different kinds on amazon and it keeps telling me that it won't for my vehicle...?

 

Never mind found them in auto parts warehouse for same price and it tells me it fits
