Review on 🔍 Denso 2344132 O2 Sensor: Optimize Your Search by Steven Ferguson

I saved a lot of money by buying the sensors from Amazon and installing them myself rather than going to any store. There is also a feature that comes with buying car parts to make sure the part fits your car, use it! I used this part on my 2002 Subaru Legacy GT station wagon with 130,000 miles. The swap took a little longer than I expected because I tried swapping it out when the system was still hot, but once installed it worked great. If your vehicle is giving out a CAT code, try replacing the upper/lower sensors first before replacing the entire system as you will be replacing the sensors anyway! No more code, better gas mileage, pretty cheap to do it yourself.
