O2 defouler

  • Aug 31, 2013 · I removed my cat in favor of just a straight pipe and now have a question about my o2 sensors. I know for a fact I'll get a CEL if I just screw the second o2 (downstream) into the straight pipe. Can I use a defouler to avoid CEL. Ideally, I'd like to get a tune but I don't have that kinda money...
Aug 01, 2014 · I'm interested in getting a downpipe but don't want to have to look at a CEL all the time. I'm also not ready for an intercooler so a stage 3 tune that turns off the CEL isn't an option. Have any of you run an O2 defouler and successfully avoided the CEL? Are there any adverse effects to...

O2 sensor defouler is a very effective tool for avoiding Check Engine Lights(CEL). Pulls the Oxygen Sensor further away from the exhaust gas stream. Have a check engine light in your vehicle for cat efficiency codes due to not having a catalytic conver
  • Now you need to screw the de-fouler onto the oxygen sensor. You want to use the one you drilled out first and simply screw it on to the sensor then screw the o2 sensor and the drilled out defouler into the UNDRILLED defouler.then screw everything back into the exhaust where the original o2 went. Should look like the pic when it all said and done.

    May 09, 2016 · The odd time i do get a check engine now it is usually because the o2 sensor is bad and not doing its job perfectly. What i have found is once you go to aftermarket header, hyperflows, and a aftermarket muffler the system is much more sensitive. If the o2 sensors start to deteriorate the stft (short term fuel trim) and ltft get near the limits ...

    Okay so I’ve had my RS for about 5 months, it’s full bolt ons with a catless downpipe and tuned on an accessport by a local tuner. My o2 sensor and o2 sensor heater monitors won’t set even after I gave it to a performance shop to figure out for a month, this shop usually works on subies and...

    The defouler is what’s supposed to make the o2 read cleaner since it’s sitting further away from the emissions. People that gut out their cats when theirs bites the dust do the same. Sent from my iPhone using Tapatalk

    Nov 17, 2013 · You can put a spark plug defouler inline with the second O2 and that will fix your issue with the catless down pipe. When I made my down pipes I used a taller O2 bung and I haven't thrown a code. Edit: threw a code today. The spacer I used wasn't large enough.

    Rear O2 Sensor Simulators are used in off road/racing vehicles to prevent the check engine light from illuminating and to prevent an ECU code from tripping (P-0420 and/or P-0430) when the catalytic converter(s) are removed for off road/racing use. URD Rear O2 Sensor Simulators are carefully calibrated to condition the signal from the rear O2 sensor to keep it in the range the ECU is expecting ...

    Wondering if I need to replace both O2 sensors. Hi there. When the codes P0420 and P0430 come up, usually the catalytic converter has failed, but before you determine if you need to replace the catalytic converter, consider checking the following: A damaged or failed oxygen sensor on...

    The defouler will move the secondary O2 Sensor away from the direct flow of gasses in the catalytic converter which will trick the computer into thinking that there is still restrictions in the cat therefore keeping the Check Engine Light from coming on.

Mar 26, 2011 · Went here and found O2 Sensor spacers (also called O2 Simulators): O2 Simulator, Cel Fix. Installed one 4000 miles ago, and NO CODE!!! Here in Georgia they don't "sniff" the tailpipe at Emission Stations on vehicles 1996 and newer so I don't know whether the cat was truly bad or whether the front O2 sensor is "lazy".
