Universal O2 Spacer with Catalytic Converter - Single

$155.95
(9 reviews) Write a Review

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. 

FEATURES:

  • Fits most makes & models worldwide (Specify Angle option from drop down above and Quantity needed for your specific vehicle)

  • Spacer available in a 90 Degree or 45 Degree Option.

  • Male end threads into existing M18 x 1.5 O2 Bungs

  • Spacer body dimensions: 3 3/4" L x 1 1/2" W x 1 1/2" H

  • Fitting dimensions: 1" L x 1" W x 1" H (not including threaded portion)

  • 1" depth of threads on fittings for adjustments

IMPORTANT NOTES:

  • For use on DOWNSTREAM oxygen sensors only

  • Universal fitment for all cars

  • For off road competition use only, not to be use on public roads or highways. Please check with your local authorities to ensure compliance with all laws

  • There is no guarantee this will prevent a CEL from triggering, please contact a Fabspeed Performance Specialsist for more details

    No CEL on 2018 BMW 340i

    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.

    CEL Solution

    Posted by GREG DUREAULT on 24th May 2018

    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.

    Very well made. Did not turn off CEL

    Posted by Gil Plumb on 18th Apr 2017

    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.

    Just What the Doctor Ordered

    Posted by Ron on 2nd Mar 2017

    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.

    Worked for a bit.

    Unfortunately, in a 2016 S3 this will not keep you CEL off if you have a catless downpipe installed.

    PASSED TEXAS INSPECTION

    Posted by Josh Goen on 6th Oct 2016

    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.
