Default Replacing Oxygen Sensors on my 2000 XJ

i need to replace the oxygen sensors on my xj, it failed emissions. does it matter what brand of 02 sensors i get? i found some for $20-$30 bucks on rockauto, and then there are Bosch 02 sensors for $40.

thanks guys.

I personally havent had a issue, others will say they have. Nice trick, run your engine till the exhaust is hot. The extra heat really helps to get those stuck o2s out.

I seek out NTK sensor for the 4.0, as they are what your XJ came equipped with.

I have no personal issue with Bosch, but there are some that have an issue and it has been traced to a slightly different resistance value on the heater circuit.

Stay away from anything universal and don't buy engine management sensors on ebay UNLESS it is a confirmed brand name! There is no lack of absolute crap junk floating around for sale on "the bay".
