Review on πŸ”§ Denso 234-9124 Air Fuel Sensor - Achieving Optimal Fuel Efficiency and Performance by John Hill

Revainrating 3 out of 5

Poor design is best for sensors

Like other reviewers, you can't use a regular touch wrench because the heat shield blocks access to the nut. I had to destroy the old one to remove it and carefully tighten the new one with pliers. So far no problems. I replaced both O2 sensors during setup - spark plugs, air filter, cleaned the MAP sensor, etc.

Pros
  • Decent performance
Cons
  • Some issues
