Review on ๐Ÿ”‹ Denso 234-4800 Oxygen Sensor: Reliable Performance for Enhanced Fuel Efficiency by David Norwood

Revainrating 5 out of 5

Fits perfectly, get ready to improvise

I bought this for a 2004 Toyota Corolla. As expected, it fit perfectly and was SIGNIFICANTLY cheaper than another brand from the local store. At the same time, be prepared to improvise, since removing the old sensor completely clogged the threads in the manifold. Use penetrating oil liberally when removing the old gauge and be prepared to purchase a tap and cutting tool kit to restore the threads. I wasn't prepared for this and so a half hour's work turned into a full day.
