i have read some threads on here about using the spark plug trick for aftermarket headers. what is this concept? i never heard of it. i have the megan header with the megan catback but stock s-pipe for now, and i havent thrown a CEL yet. but in case i do, whats the story behind using a spark plug? thanks

 

Use a spark plug anti-fouler on the O2 sensor. It spaces the the sensor from the stream a little and will read a stream that is more in line with what it'd normally read.

 

brand is help, available dirt cheap at any auto parts store.

 

quick question though....the anti fouler goes in the s-pipe or the headers? cuz ive heard both now and im a bit confused. my headers are coming in next week so i need to go buy one and put it in.

 

the sensor on your header is your afr sensor

sensor on the spipe is o2 sensor <--- anti fouler goes here

* be very carefull taking off the afr sensor beacause many including me have stripped it. it cost 170-220$

 

ouch. i was thinkin of just takin it to a shop to do it cuz im afriad of screwin it up like that. what do u suggest if i end up doing it myself? any tips on how to get the afr sensor out without screwin it up?

 

wd40.

take your time and be happy camper when your putting it on. you learn more from doing it yourself.

too long of a wrench , you put too much torque on the nut, then u screw it up.

too short of a wrench, you'll have calluses.

 

I bought the tC CEL Light Eliminator throught MMW, and I haven't installed yet, I think it goes on my header, or does it go on my S-Pipe?

 

Anti-Foulers GOES on the SPIPE

Spipe

goes on the SPIPE

SPIPE

 

HAHA i hope everyone gets it after that post.

 

just FYI, the package says HELP on it, but the actual brand is Motormite...just in case you are lazy and want to but it online. The part I think is 42009 or 42002. One is longer than the other but dont remember which one at the moment
