hr test pipe non fouler fix
 

Ok there are some rough picuters but you will get the idea.

to start off, wish i had take pictures. do a search if you don't know you will find out about using spark plug non foulers to fix the cel light from test pipes.
i picked mine up at napa i think for 2.59 for a set and you will need 2. you will need to drill them out one all the way thru the hole and almost to the bottom in the second one. but don't go thru the second hole. now i didn't realize i bought 2 different kinds. the holes are 2 different sizes in the bottom. try to get the ones that have small holes.

ok get a brillo pad, your gonna want to rip it apart and shake it to try to get the soap out. you won't get it all but its ok.

the dark one is the old one that was stuff in the non fouler, it was an inch big, packed in there. pack it very well. each time you stuff it and pack it, blow thru the non foulers. it will be kinda hard to blow thru. just to give you an idea you will use almost all of the brillo padding. sorry my write up isn't better, but for those that have used non foulers in the past you will know what im talking about. those that don't please feel free to ask.

How long have you been using this? thx for the simple write up. If this fixes the CEL for good I wont have to worry about emissions here anymore.

ive been running for about 2k miles. i was getting a cel again, but when i pulled them apart i saw that i had the 2 different holes. so i went and bought another set that has the small holes. but yes the fix is great and works.

Anyone who wants a set of these made ill make ya a set for 20 bucks shipped.

I want a set!

How long will it take to ship out?

PM me with Pay Pal details, thanks.

hold on for a min
i had the non foulers installed in my car when it wasnt filled and my car still bogged and CEL was still on...


so ur saying if u stuff the non fouler with that pad the CEL and the bog goes away?

Better pictures and directions in the DIY section.

Instead of knocking the soap out of a Brillo pad, why don't you use regular steel wool?

Steel wool will not work its not fine enough. If you look at my picture you can see a ball of it sitting there that would not work. .


I can't promise your bog will go away. I just know I don't have bog or a cel. But I also don't have test pipes with stock exhaust. But when I did have my stock exhaust on waiting for my jic. I did experience big even with the fix and no cell.

Your local hardware store will have the correct thickness you are looking for in the section that has the sanding material (paint department).

Ill check the hardware store.
But I received my berk high flows today and the o2 bung that is built as a non fouler has a small hole like the ones we make for our cars. When my gaskets get here im going to stuff it with steel wool or brillo and see how that does before I use non foulers in it.

Is this still working for you?

I remember other members trying this with test pipes a while ago and nobody was successful. I couldn't find the thread with a quick search, but will post a link if I find it.

Hydrazine was trying to develop a fix but I don't think anything ever came of it...

yes it works fine. i had trouble on one side but found out it was due to one set of non foulers having a big hole in it. the side that had a small hole looked decent and still nice and compacted when i pulled it out. the other side i could see looked rough and like some of it had blown out. im running test pipes now with just the berk non foulers. i put a little stainless wool from lowes in there as someone suggested and its working like a charm so far.

I just bought some berk tps i notice in the pics theres a tube coming off, is this the non fouler ur talking about? Should i forget about buying the non foulers from pep boys and stuffing this tube with brillo?

im fixing to pull mine apart and see. look inside if there is a small hole then just stuff it till you can barely blow thru it. if there is a big hole then you will need the non fouler im fixing to go pull mine apart and see how they look. i stuffed my high flows and 200+ miles and no light yet

Ok its confirmed the berk test pipes and high flow cats do not need non foulers. you can just stuff non fouler made on them with stainless wool. on the test pipes stuff just enough that you can barely blow thru it. on the high flow cats, use a little less to take up for the fact it has a cat. also on the high flow cats do not stuff it hard just set it in there and let the o2 sensor hold it in place as there is some clearance that will be there if you stuff it and cause it to blow back.

So dont stuff it like hell? Stuff it till you can still hear barely any air making it through?

you want a nice pack in there. but yes barely able to blow thru. haha i wish i had read about the brillo before i had installed. i would of checked a long time ago. but after checking the high flows, i figured the test pipes were they same and they are.

No SES light from this set up either:

did you stuff those or they naturally dont produce a cel?

Aam throws a cell also. I wrote berk and asked them about putting a smaller hole in there pipes to try and fix it all together without stuffing.

The J-bends hanging off my test pipes are hollow.

How long have you had them on the car?

They were put in the same time the TT was, so it's been about 6 months.

I put mine on yesterday, but forgot to get the steel wool. If it comes on like it probly will ill do it then.

lol nice. well my high flows have been on about 300 miles+ and i have no cel or a sputter like most are getting

I got test pipes, honestly im hoping I get used to the rasp between 2-3k if not ill probly get a turboxs catback sooner then later. Outside it sounds ****in sex tho.

i would not recommend the truboxs with test pipes

really? hmmm thx for the heads up. Cel came on btw, will be puttin brillo in this weekend probly

I have an 08G35 Stuffed with brillo it came on after 500+ even with non foulers

Your rasp ain't goin away no matter what. U gonna havta get use to it. I kinda got use to it. My exhaust does cover up some of the sound.. But it's always there.. It sux. N sux the brillo didn't work.. Any ideas what we can do now??

I didnt do the brillo yet. Kram said it worked, i just been lazy and havent gotten around to it yet. After a week of driving the rasp has actually mellowed out quite a bit in normal driving. Its barely there between 2-2500 but when i stomp on it, its there.

but how did you stuff. it i tried and tested it till i got the right combo and the light did not come on.

i am working on something to try to fix the cell issue, i just gotta figure out a way to make it work.

I used very fine steel wool from Home Depot. I stuffed it PACKED! Barely enough to blow through the hole and had to use clamps to put in sensor.

:(

I have one more fix that was sent by a member on here and I will keep you updated if it works it.

and wat method was that

clamps ?? i don't understand. what kind of testpipes or high flow cats are you using?

GTM is selling the test pipes with the j-bends now:

https://my350z.com/forum/product-ann...est-pipes.html

look good but has anyone tried them to prove if they work or not. ill stick with what im using and what im trying to make.

I have the GTM prototypes on my car and all's good. I'm sure others would still curious to see if your solution is more cost efficient though.

yeah its gonna be very cheap to those who already have test pipes and high flow cats. i need to get some time off work to go shopping so i can see if they even have the sizes im looking for. once i know it works ill let everyone know.

hmm, ill be ordering tps soon, just got an 07, keep us posted on some fixes

bump any updates from anybody?

i have a question regarding high flow cats, a friend of mine said to get tp's instead of hfc's due to the nismo exhaust i have on my z tends to over time blow the substrate material in the hfc into the midpipe. is there any truth to this? i dont want the rasp that comes with tp's but i dont know enough about the the updated versions of hfc's for the vq35hr motor.

nismo exhaust with Test Pipes.
wayyy to raspy!

high flow cats to do have a substrate material they are either metallaic or ceramic. they are not like mufflers or resonators.

was that in cold start?

but on the new motor and new designs of the hfc's does the material get blown out of the hfc's after time like they did in the hfc's for the vq35de designs
this is the reason im hesitating on the tp's and hfc's

Everyone gets that hesitation, you need a tune. I got it last week pretty bad trying to jump on a highway and floored it in 3rd. That could have gotten ugly really fast.

ahhHA! I used steel wool, I'll give her a try again with some brillo

thanks

I think imma give this a try, even though my CEL doesn't bother me. Thx for the help kramykram:)
