Does anyone have any experience with using an aftermarket O2 sensor near the turbo?

 

Bump! I would like to know also.

 

Also looking for info.

 

Im using the Universal Bosch. Had it on for almost a year now and no problems. $60 shipped is what i paid

 

the only thing i don't like about Universal o2 sensors is the wiring. You better wire it right( Soder all the wires) just speaking from experience.

Wiring instruction there. I've used a few aftermaket o2 sensors and when rewiring I've never really soldered, just made sure the connections were tight and then used a good amount of electrical tape and that's always worked out ok.

 

I didnt solder mine. They actually give enough wire that where the wires connect are under your plug cover. Therefore they never move. I have the Universal on the Front and Rear.

 

I heard that the after market O2 may mess with your fuel trims. I was wondering if anyone had heard this also. I found a place online that sells NTK O2's for $90.00. www.sparkplugs.com

 

Is the universal Bosch o2 senosor for the evo 8 compatible with the evo 9? Anyone know the difference between the two?

 

I have a Walker stock replacement from oxygensensors.com. it works fine and has a longer cord than the stock. dont quote me on this but i think the bosch and universal type o2 sensors dont come with the harness and u need to cut/connect/solder your stock one to the new sensor. with a damaged o2 sensor u run hella rich so i was burning a tank of gas in about 150 mi. when i replaced it with the walker one i immediately returned to my normal 220-230mi/tank...

 

With the NTK sensor it is suppose to comes with the correct plug so you do not have to cut any wires. Straight plug and play. I should have in next week.

 

Sparkplugs.com is still out of stock of the NTK O2 sensor, so they will be sending me the Denso O2 (part # 234-4741). I spoke to the tech support at denso, and they assured me that is should work just like the OE part. Denso also stated that they make many OE O2 sensors.

 

mine from walker took a crap in a month is that cause of my set up or something wrong with something else
