$5 o2 cheater/non fouler how-to

[tran03]

Just wanted to say that I tried this on my 350z and it worked perfectly.

My EVO came with an expensive 02 simulator so I didn't have to worry but if my car didn't have it, I would of done this non fouler/cheater mod.

Have any of you guys ran track days with this installed? I would like to know if a CEL is possible while hard driving

[joon82]

where can I get the 90 degree bend? I'm keep getting rattle from bottom. I tried banging the body with hammer but still getting rattle at high speed.

i guess you didnt search that hard = How to install the spark plug anti-foulers to remove the ses or cel light

hey guys, i did all of the steps in the how to and my CEL is still on. I read my codes and it is still my 02 sensor. Whats the problem?

[AWDTurbo4]

did u disconnect the battery first?

also, try the longer ones, there are some threads around here with the part number on those.

I used 1 long and one short.

[20lbsboost]

well i forgot to disconnect the battery first but after i put together the two short non foulers and connected it to the 02 sensor i reset it. The CEL doesnt come on right after i turn the car on, its when i turn the car off and then on again is when it comes back on

[AWDTurbo4]

try the longer ones then, part#42002


or 1 of each

The two spark plug anti-foulers will not work with Buschur's exhaust. It hits the bottom of the car and you cannot rotate the cat-back without hitting the bumper with the muffler. Will just one anti-fouler work with no cat?

The o2 housing has one of the o2 sensors. Depending on if you have a Evo 8 or a Evo 9 that would determine wre the secondary o2 sensor is located. On the Evo 9 the secondary o2 sensor is located right above the cat which has a flat cut on top of it.

On the Evo 8 the secondary o2 sensors is located ion the rear section of the cat -back.

Do a search on my name, I posted many pics in the past displaying the different locations of the o2 sensors on the Evo 8 and Evo 9.

I have an Evo IX MR and I just bought an Espelir JGT500r catback and an Espelir downpipe. I am also going to install a test pipe. Since there is one o2 sensor in the o2 housing and another located right above the cat, what can I use to plug up the now redundant third bung that came with the catback itself?

[hondafan]

usually, any exhaust piece you buy that has a bung in it, also includes a plug for the bung in case you're not using it.

[Gumpy]

Because the 2 anti-foulers did not work with Buschur's exhaust. I took the one that the O2 sensor screwed into and braised a washer on it and made the hole even smaller to try to keep the gas that reaches the sensor to a minimum. I will let you guys know if this works for those of you who do not want to bang the crap out of the underbody to get the 2 anti-foulers to fit.
