I hear they have some good prices though Ive never purchased anything from them...Def. Go Dealer OEM with this part though. Subarus are very touchy when it comes to certain aftermarket components..axles,thermostats,o2 sensors..just to name a few...How many miles are on the car? What year is the vehicle? What mods do you have?

hmmm well if its throwing a heater circuit code I would prob go ahead and replace the sensor ( thats me ).... how many miles are on the car? It is somewhat common to see the front o2 sensors on these cars take a crap after some miles...
