Oxygen Sensor Brands

[mikejwil]

I have found O2 sensors from SNG, Bosch, and Denso. Does anyone have experience with the quality/reliability/fit of these? Any idea what brand Jeep installs at the factory?

These are for a 99 XJ 4.0L. I found good prices on autopartswarehouse.com. Any other good sources?

Thanks.

I'll typically use either Bosch or ACDelco - but I'm picky.

My 1998 4 liter had NTK (NGK brand of O2 sensor), and the replacement sensors I got at the dealership were NTK.

Bosch. AC-Delco if really needed, but otherwise Bosch.

the factory uses mainly NTK (NGK) and also denso

i think in the 97-00 xj it was mainly NTK
