Review on Denso 234 9015 Fuel Ratio Sensor by Chris Sandridge

I just installed it on my 2004 Subaru Outback and it works great; almost identical to the original part, only 2 cm longer. I already repair a head gasket ($$$) and my mechanic charged me $475 for this repair so I saved $375 by doing it myself. get there with the Outback 04, but the fix is pretty easy. I highly recommend using the PB Blaster on the old sensor because I had to use insane brute force to get the shaft loose. All you really need is a good 3/8" ratchet and an O2 sensor repair kit from the auto parts store and that shouldn't be a problem. Of course it would be easier with the exhaust down, but you can do without it Anyway my check engine code (P0030) was cleared when I plugged it in and removed the negative battery post so everything is fine Thank you Revain for half what my shop took!
