I ordered some NGK plug wires for the 97 OBW 2.5L to try to overcome the "Subaru wires for this car are too short" problem. While I was on the NGK site, I noticed that they make an "OE identical" front O2 sensor. So, I ordered one. The package is en-route, and I am second-guessing myself. I know that EOM is recommended for that front sensor, but this is NGK. Subaru and NGK are like peas and carrots aren't they?

 

Seriously, any experiences with NGK O2 sensors? Am I just asking for trouble if I put it in? I'm replacing a part that may not even need to be replaced in the first place here. Mine has never thrown any codes, or caused real problems. I just noticed that I was getting a few less MPG's last fall, and was trying to figure out why. The one in the car is the original - 197K.

 

Thanks

Give it a shot. Tell us if you gain some MPG.

yeah cant hurt anything if it acts up just throw the old one back in....my suby has 190,000 on the original front 02 sensor......im intrested to see the results....

I'll change my name to ginny-pig.

what did you pay for it?

What site were you on? I looked on the NGK site and there isn't any ability to order the sensor. Please post the link.

This is not the NGK website, but they sell NGK plugs, wires and O2 sensors. The site is kind of a pain to use, but they were one of the few places that actually had the wires I wanted. I don’t think this is the cheapest O2 sensor out there, but it wasn’t worth paying shipping from another source when I was buying the wires anyway. I think it was right around $65. The OEM's that I had looked at were all at least that much.
