2007 Peace, mercy, and blessings of God be upon you. I have two Taiwanese sensors for a Mazda 3 2007 1.6. The sensors were bought from AliExpress for 50 SAR. The first sensor is front with the connector for sale for 30 SAR. The second sensor is rear without the connector for sale for 20 SAR. The two sensors are working fine. The reason for selling is that I installed them on a Mazda 6 2007 2.3 and they didn't work for me because I thought they were the same due to the similarity in shape and connector. I changed the first sensor for a Mazda 6 2007 Taiwanese, and it made a difference in fuel consumption because the first one was carbonized, and the second one, you can remove the old connector and install it. It is not returnable due to the small amount. I'm not offering it for 100 or 200, it's up to you 😅
