B6 S4 oxygen spacers

[durrmcdanks]

Was wondering if anybody knows of someone who sells oxygen spacers or does custom oxygen spacers for a b6 s4. Thank you.

vastperformance for the o2 spacers or you can make your own with spart plug arrestors.

[durrmcdanks]

thank you

[trexturk]

yea spark plug non foulers i think thats what they are called.
you can get them at autozone.

[Justincredible]

tried the auto zone route no go they don't work.

I have the Vastperformance ones they work the best for me. I might get a CEL if it gets real cold and the car has an issue cold starting. But no other issues and no CEL

i used the autozone ones on mine. no cel after 5k miles
you gotta drill the one so the sensor can fit inside it. then screw that one into a nondrilled one.
kinda like this
(pic i found online)

thank you. I believe i will go with the VAST route.

[ginkof]

what is the point in doing this? what is the check engine light from?

[Justincredible]

If you remove the cats. You will get a CEL. The eliminators VAST eliminators prevents the CEL threw placing the secondary 02 in a position that results in a 02 reading the same as it wold be if you had a cat in.
Proper placement is super important because you might be able to stop the CEL with a non fouler but you might still have an issue with not having the proper LTFT (long term fuel trims) getting that part of the signal correct is also something you need to look into.

Obviously the car is not going to be seriously effected either way. But for me I thought it was important

[durrmcdanks]

and no cats means more hp and bigger sound

the vast eliminators are essentially 2 o2 bungs welded together, with a o2 plug welded to the bottom and then drilled out. its essentially the same at the non foulers, just measure it up and you can get the correct spacing.

[Justincredible]

just measure it up and you can get the correct spacing.

the spacing and the hole were 2 things i didn't want to mess with. so for me a much better way to go

[durrmcdanks]

you didnt want to mess with the VAST spacers or the spark plug foulers?

[Justincredible]

the spark plug foulers F that.

The Vast ones are plug and play the foulers you have to mess with and keep trying to get the set up right. I have never had good like with them in the past and I Just wanted a Drop in solution. The Vast ELE's went right in and no issues. The only thing I had to do was to pull down the extra slack that is in the 02 wires. But you would have to do that no matter what type you used

[durrmcdanks]

The Vast oxygen spacers didnt work.

[Justincredible]

Ya mine gave me an issue the other day with the cold weather. Check your codes and see what it says. Post that or P.M. me if you wish.

I fixed mine. I looked at the code. Basically it said too much exhaust. So I put in some washers. If you have aftermarket Dp's then some of the guys seem to need to put in spacers as well.

Get the codes that will tell more

did you use spacers on all 4 o2 sensors or just the two? make sure you buy all four because these cars are smart and hard to fool. you can get the two but after 200 or so miles, you'll throw a code

[nimski62]

How hard is it to reach the front o2 sensors??? One of mine is bad and I am scared it is impossible to get to.

[91gl]

with a lift it is pretty easy to get to

[WinterRunner]

Why not go the Wayne route? The guy makes 90 degree machined spacers for our car. Mine run perfectly, no cal, no problems, and they dont look too bad either. You have to search for the thread, but they are the best ones Ive seen to date.

I only did my back 2 with the Wayne O2 sensors, not a CEL thrown after 10K miles.....

[WinterRunner]

The Vast oxygen spacers didnt work.

I second that, the sensor would "bottom out" before it was fully screwed in.....

any info on the wayne spacers?

[durrmcdanks]
