TEST PIPES ON 04 AND CEL

[Sundeviljay]

i think it depends on if it was an '04 or an '04.5

[KrazyKorean]

I used the spark plug fouler on my s2000 megan test pipe and driven over 5k so far and there is no cel yet. Has worked for everyone so far that has a testpipe on a s2k and its a 2004

[KrazyKorean]

Also which spark plug foulers are bought there are a few ones. I know on the s2000 its the 42002

I have a 2004 and the CEL kept coming on, even after I reset it. It would come back on after 20 to 50 miles. I tried the spark plug non fouler and it works, been around 3000 miles now and no CEL. I bought two sets because I read that you need to stack them for it to work, but mine is working with only one adapter on each O2 sensor. If you need a a set PM me and I'll sell it to you, it's already drilled.

[KrazyKorean]

No its cool, I can drill them out myself, plus I am going to do this tom or wed.. Can you tell me which ones you bought..the number is on the top right corner of the packaging, thanks

spark plug defoulers. the cheapest and easiest anwser to the SES light when adding test pipes. can be picked up at your local pepboys for 2 dollars. dont waste your time with the o2 simulator box.

i had testpipes on my car at one time. the day after i installed them the SES light came on and i installed the sparkplug defouler/o2 sensor spacer, reset the ecu and the SES light stayed off.

gl with your testpipes

Nope. No modifications or aftermarket replacement of the cats are CARB legal.

You won't ever get a CEL because you still have cats on the car. You get the CEL if you remove the cats because you have a front and rear 02 sensor. Without the cats these read the same since the cats have not "cleaned up" the exhaust so you throw a code. Now on my brothers Mustangs you can purchase a MIL extension which interrupts the signal from the 02 sensor and tricks the ECM into saying everything is good so no light, but they have tunes and the rear 02 sensors are just turned off so no problem.

No CEL on my '03 (so far...crossing fingers). Didn't use non-foulers or 02 simulators either...

ok im bringin this back from the dead but i searched and found no answer, does anyone have the part number for which spark plug defoulers to use, im currently using them on the race header on my rsx but im going to be putting test pipes on my friends g35 today so im not sure if they will be a different part number

[BuyakashaDC5]

ok so i figured it out myself so for anyone who wants to know the part number for the spark plug defouler is 42009 and if anyone didnt know the kinetix racing test pipe doesnt need one

[PSD G35]

I just installed FI 300 Cell cats about 500 miles ago. you can see from my sig what year my car is. I have not thrown a CEL yet either. K.O.W. I was also sure to be extra careful with my O2 sensors when I took them off.

good luck
