*Update* O2 Sensor Spacer

jmwilson125 · 01-17-2016, 12:31 PM

Hi guys,

So recently I just got a CEL after installing my high flow ER cat.

Has anyone used an O2 sensor spacer successfully yet? Do you reccomend any in particular that are of great build quality?

Are there any cons to doing a spacer?

*Update* straight o2 spacer would not fit. It ended up hitting the heat shielding. 90 degree sensor fits but throws a different code. I forget exactly what it was p103 maybe?

Looked it up and it says basically there is too long of a delay in reading the second sensor aka it still knows somethings is not right.

Well I just ordered a stainless one on amazon for roughly $15.

I will install and report back my findings.

Not sure if Im allowed to post a link, but check out big daddies garage on the web. Guys in the 4 series forum have had great success with the mini cat spacer.

*update* I tried installing the spacer last night, but I could not get the cat back in place with the spacer. Or ordered a 90 degree one and will be trying that this weekend.
