Anyone know how to install this thing?
It looks pretty straight forward, but I don;'t understand what these three metalic item or that rubber horseshoe is there for.
Answers?

 

Maybe this picture will help...



As for the three different restrictors & lock ring you received with the O2 spacer, try the middle size one first and secure it with the lock ring inside the spacer. after that it's just a matter of installing the O2 spacer into your pipe, then installing the O2 sensor itself into the spacer (don't forget to use some anti-sieze for this). If you end up getting a CEL even after installing the O2 spacer, you may have to remove it and try one of the other sized restrictors.

 

Your awesome, thanks I'll give it a whirl in the next few days.

 

i'm using the smallest restrictor now. had for 2 days w/o a cell. i'm using ams hfc

 

Running the exact same, we'll see who's light pops on first!

 

using the mid sized restrictor, no CEL so far.

 

ive had the smallest restrictor in for about 2 months with no cel

 

I have the AMS downpipe and the AMS HFC. Put the spacer on the HFC and the CEL came on. DO I need to put 1 on the downpipe?

 

make sure you clear the cel first.

if it still comes on use a different spacer.

 

Guys On AMS website it show a pic of the spacer. Isn't the spacer just a 2 or 3 dollar antifouler? If it is seems like 25 dollars is a little much!!!

 

I did clear it and then put it on. Im using the smallest 1

 

did it work

 

you're right. it's exactly what it is.

and you're right, it is a bit much. i'd opt for the touge factory L type...but i wasn't smart enough back then.

 

no the light is still on. do i need to put 1 on the downpipe?

 

no; putting it on the downpipe has no effect whatsoever.
