Review on 🚀 Upgraded NTK 23099 Oxygen Sensor for Improved Engine Performance by Raymond Vogel

This lower sensor fits my 1999 Jeep Wrangler TJ Sahara perfectly. The hardest part was removing the old one as it was very stuck in there. I ended up cutting the wire and using a long 7/8" socket. A regular oxygen sensor head is fine for tightening a new one. will need to be replaced again. I replaced this and the NGK 23151 upstream sensor at the same time. Definitely worth it Case of buying these OEM NGK sensors (NTK) instead of aftermarket brands like Bosch.
