Mods please forgive me if I posted in the wrong section



Good afternoon.I came across a vibrant part number 11621.this is the link...

Its a spacer so the cel don't go off if u needed to run a gutted cat or test pipe for the track.has anybody used it?

Our cars rear o2 are not very sensitive, I ran the rear o2 in a strieght pipe with no code. I made o2 extenders just like these for my supercharged f150 to get rid of the rear o2 code and it worked perfect. The other option is to wire in a resistor that tricks the ecu into thinking the sensor is working, I did this on my wrx with great results.

if your paying $25 for that. your getting ripped off...go to vato zone, & get a anti spark fouler. they are like $3 & its the same thingq

I kno about spark plug foulers.ill give them a try.my cel will turn on with a test pipe so I was looking into spacers.will try it out.I have a chipped ecu to disable the rear o2 but light goes on anyway.ill let you guys know how everything works out.thanks again

researched on the forum and found out that the doorman anti spark plug fouler number 42002, which will work for our vehicles cats, will only work for the fat bungs 94 and older.96 have skinnier bungs m12 1.25 . found out yesterday on the attempt to install the doorman 42002 on the cat.i know that m12 1.25 is the thread size .looking through to see if they make this size

I have been running an anti fouler for a year know with no CEL for the rear O2. Even before I got the fouler my CEL would only come on if I was really getting on it. If you can get a fouler for the correct size you will be good, not sure if where or if they have the size you are looking for though.

if your ECU is chipped & has the rear o2 deleted, then there is something wrong with the ECU,...or somone lied to you & told you the rear 02 was deleted..

Im starting to lean to that as well.ecu has the same codes for a year since swap with 3 not ready.
the ecu was purchased a while back from a forum member.them I sent it to calum.long time ago .
Thinking maybe I have a short somewhere

THere are two types of rear 02 sensors. A fat one and a skinny one. Verify which one you have as the link is for the fat ones only i think.
