I replaced my header with the Surewin header, and I got the second O2 sensor out with a little persuasion. But I found that the threads were gummed up, so I didn't want to mess up the threads of my new header, so I've been running on the primary O2 sensor for about a week now.

My question is... to replace the O2 sensor (toyota part number 89465-20460)
Can I use either of these from Jegs?
Denso 234-2000 or Denso 234-2010

Reason being that I'm exchanging things and will have about a $20 credit that could go towards my replacement O2 sensor. Otherwise I will just order a new one from 1sttoyotaworld $107.75

correction, i actually looked at the O2 sensor that I took off my car and it says 89465-20420 which is the california spec O2 sensor.
below it it says Denso 4383. so it looks like those O2 sensors probably won't work. Darn.

Who would have thought that a Cali spec Celica would have made it out to St. Louis.

getting one from toyota is a sure fire way

who thought a cali spec would make it to Hawaii??

I know that toyota is a sure fire way, I was just hoping that I could take advantage of a $20 credit that I'll have coming my way.
