Review on πŸ”§ Enhance Engine Performance with Denso 234-4642 Oxygen Sensor (Air and Fuel Ratio Sensor) by William Mathis

Revainrating 4 out of 5

Fits 2003 Mitsubishi Lancer ES

The hardest part of installing this sensor on my 03 Lancer was removing the old one. I had to remove the catalytic converter with the sensor still attached and take it to the shop to have it removed. They had to use a flashlight to take it off. After the old one came off I was able to put this one on and adjust the rubber seal properly and it worked fine. I'm only giving 4 stars because it takes 22mm to shoot and 7/8 a little more, and once it's rusted in place from heat and humidity it won't come loose.

Pros
  • Very Good Price
Cons
  • old
