switched out my dp today to a catless one, was taking out the precat o2 sensor, and well somehow it was stripped in there because it came out mangled! was super tight to turn out which is odd and I'm not sure what caused this to happen since it went in smoothly during previous install. I am scheduled to get my car tuned tomorrow so if anyone has a precat o2 sensor for an 07 wrx let me know. Need asap and early in the morning if possible.

thanks for looking, chris

 

Bump for Chris. Sorry to hear this man

 

Capitol Subaru, Stevens Creek Subaru?

Hit up Unit91

 

Hi i'm Sammy i sell autoparts and i can get you a o2 sensor for 07 subaru wrx is it a auto or manual Nippon Denso should be NIP: 234-9120 160 for manual brand new. hope that helps i'm in SF. 415-609-0332

 

thanks guys, missed my tune appointment but got the o2 sensor for 140 out the door, damn those little things are expensive.....

 

and thanks scooby snacks i happened to get one from winchester auto that is close to me.... good lookin out tho

 

I see this is resolved but cant you pop a 8ohm capacitor in there and have it work?

 

the bigger issue was that there would have been a hole in his dp... when we went to swap the pre cat o2 sensor from the old dp to the new, it was siezed so the threads got messed up... we didnt have a plug for the hole... and he needed the o2 sensor to get his tune today...

 

the downpipe only has a post cat o2 sensor. the precat sensor is in the header and then a egt sensor in the uppipe. but im glad you got it fixed

 

Man he should have hit you up Anthony,you could have hooked him up..what you tell me? 70$ for the censor?

 

yup 70 bucks for my 02 sensor. o well as long as he got it fixed everything is good.

 

$70 for my 02 sensor also but you dont need it anymore

 

hengmen you are wrong, the 02 sensor on an 07 wrx is in the top of the downpipe and behind the turbo, under the heat shield, then there is one after the cat..... wish you guys posted a lil earlier would have saved me some cash but its all godd she is up and running now, full 3" and catless. She sounds like a beast!

 

thanks again for the help jamison! Tune will be next friday at 4pm. see if I can hit the 300whp mark =). Think i'll be able to hit that now with my setup

 

ive never seen an 07wrx with a o2 sensor on top of the top portion of the downpipe. must be because of your jdm exhaust setup? i work at stevens creek subaru as a tech and i have NEVER seen a o2sensor on the top unless it was a wideband o2 sensor or a jdm setup
