Review on πŸ”§ Improved Denso 234-5430 Air-Fuel Ratio Oxygen Sensor by Danny Porter

Revainrating 5 out of 5

Mine came out easily I hope you do too

Used on my 2005 Hyundai Elantra which is in front of the cat. Everything fitted and matched well eliminating my P2626 code. Remove the heat shield if possible, soak the pre-existing O2 sensor threads with a penetrating oil like PB Blaster overnight, if not as soon as possible. Although there is a risk of burns, be sure to run the machine beforehand to warm up the engine to allow the metal to expand for easier removal of the old sensor. For extra power, use an adapted O2 sensor socket drive with a pull rod or brake rod. It was easy for me, I hope it's the same for you.

Pros
  • Nice little thing
Cons
  • A little change
