Review on Enhanced Denso 234-9120 Air-Fuel Ratio Oxygen Sensor by David West
Engine code fix P0031, 2006 STi
Perfect for my 2006 STi. A P0031 code for a bad heater element was fixed, but I swear the car now idles and pulls a little better than it's ever done on my property. The old clamps are very difficult to remove from the wiring harness bracket on the engine, but the new clamps are positioned exactly to attach to the new wiring harness. the set is perfect. It also came with a small copper ant whistle which is a nice touch. Uses a low profile TEKTON 47749 O2 socket and it did the job well considering the range is a little awkward.
- Expensive but decent
- Disappear
