Universal O2 spacers with real precious metal Catalytic Converters lengthen the distance between the O2 spacer(s). We've taken our spacers a step further by having built-in catalytic converters to allow the ECU to properly read exhaust gas and perform at optimal performance.
Oxygen sensors can occasionally trigger a CEL on stock vehicles due to the new advances of technology and would require an O2 spacer to bring the vehicle back to equilibrium and allow the ECU to read exhaust gases within the proper threshold.
Two fitting options and the two-piece design allow for complete adjustment to get the best possible fitment and results.
Read about MotoIQ's 987.2 Cayman S track build that used these O2 Spacers
I got a catted downpipe no Tune, and used this to eliminate the CEL notification. So far has been perfect no issues thus far, and highly recommend it.
I installed these spacers using the 45' option with new downstream O2 sensors and it appears to have resolved my frequent CEL issue. The car is a 2005 997C2 with Fabspeed exhaust system running a GT3 tune to the ECU. Seems to run just fine with these spacers.
Clearance was tight on retrofit. Special 22mm O2 wrench had no clearance so I made my own shortened flare nut wrenches by cutting out enough of the box end to fit the fasteners - install access problem solved.
I have a 2013 Genesis Coupe with an ISIS downpipe. I bought the Fabspeed mini cat to turn off the CEL. The product is very heavy and well made, but it was not successful in turning off the CEL. I still get the CEL codes 1140 and 0430. I replaced the downstream O2 sensor just to make sure, but still no luck. I am going to try a longer spacer next. If that is successful, I'll come back and note that.
I installed them on my 991.1 that had the IPE titanium exhaust sytem and up to date no CEL
When I replaced my stock cats on my 911 with an X pipe I knew there would be CEL's in my future. I decided to be proactive about the situation and found these O2 spacers w/ cats cells from Fabspeed. They were a quick bolt on to my new cats and fit w/o a problem, tho' you do need to try a few different alignments to clear the rear heat shield. Once installed they have worked perfectly. No CEL's! and lots of new power from the new cats. Nice work Fabspeed, a high quality product.
I put these in with on my 991 with race headers and no CEL Lights! Build quality is excellent, and you can tell they are built to last.
Unfortunately, in a 2016 S3 this will not keep you CEL off if you have a catless downpipe installed.
These worked like a charm on my '11 M3--yes some mods to heat shielding needed to make the installation but the 45 degree adjustments worked perfectly to make them fit.
I put on Fabspeed cat bypass pipes and these new O2 spacers with mini cat. The look awesome and no CEL(check engine lights. Car sounds amazing. Thank you Fabspeed!!! :)
