🔧 Improved Denso 234-5430 Air-Fuel Ratio Oxygen Sensor Review

This item is listed as 234 5430 but it is actually the 234 4336 version of the Denso O2 sensor. It doesn't fit my Kia Specter 07 and I had to shell out $180 from AutoZone for the right part. On the other hand, Revain was kind enough to send me this after my previous order for the same part (but used and cheaper) got lost in the post and made up for the difference in price. Too bad this part was mislabeled as I could have saved so much money if this was the part I need as she claims.

I turned on the check engine light and found it to be the upstream oxygen sensor. The dealer wanted too much and Advanced Auto charged almost $60 more for this part. Revain has the best price again! Denso is a good quality product and fits my Elantra perfectly! To remove the real sensor I had to remove the heat shield. I used a PB blaster to take off the shield and part and everything was smooth. Please see some of the photos I have included with the product for more information. Also contact…

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

I had an engine fault code on my Hyundai Elantra that indicated a bank 1 sensor was stuck lean. I checked for vacuum leaks and couldn't find any, the fuel pump and filter were fine so the next suspect was the oxygen sensor. I was on the verge of buying a few cheap models ranging in price from under $30-$35 and a little over $100. After reading the reviews I decided I wanted something that would last more than a few weeks so I got this one. Direct fit, comes with anti-seize compound, all you…

There was a CEL which indicated my O2 sensor failed most likely after 140,000 miles. I was lucky that the replacement took about 30 minutes with the right tools, borrowed from an auto parts store, and the part wasn't "hot welded". thread, but do not specify what is the small, unmarked, copper-colored "grease" bag that came in the box (this is the anti-seize to use for this application, as that type is the sensor not contaminated) or that there is something else in the box besides the O2 sensor.
