O2 Sensor Plug / (12mm Mild Steel)


Product Description

Sold as singles or choose quantity 2 for twin cylinders.

These are required when deciding to remove your stock 12mm O2 sensors. This would be in a situation where Rottweiler Performance Fueling Dongles or a Powercommander V is being used and the stock narrow band O2's have been rendered unused. Mild Steel is our most economical choice but has a tendency to rust. If that’s a concern than our Stainless Steel or Titanium bungs are better options.

Bikes that use 12mm O2 plugs:

  • 14+ KTM Adventure Line (ALL) x 2
  • 14+ KTM Super Duke R/GT (ALL) x 2
  • Husky 701 (ALL) x 1
  • KTM Enduro (ALL) x 1

 Bikes that use 18mm O2 plugs: (Available in titanium, stainless or mild steel)

  • RC8
  • All 990s

  1. Hey, it's a screw! 4 Star Review

    I R & R'd the exhaust sniffer, during my PC-V install. It went on without a hitch. No codes were experienced. Did what it was supposed to do.

  2. O2 Bung - stick it in the hole... (where your lambda were) 5 Star Review

    Pretty straight forward really...
    Great price, high-quality fabrication, comes with copper washer. Ace!
    If you're fancy, go for stainless, I went for form-follows-function. Copper-grease is my stainless.

  12. excellent choice for 1190 Adv R ... at altitude 5 Star Review

    Posted by on 3rd Oct 2017

    since the 1190 Adv R runs lean, at altitude this can make engine run pretty hot. making this mod both enriched the mix (there was an aroma of gas on the first ride afterwards) and allowed the engine to run a little 'cooler'.

  13. good product 5 Star Review

    Posted by on 14th Apr 2017

    Good product

  14. Hard to mess this up, worked perfect. 5 Star Review

    Used on a 690. Cleans up the wiring and works great with the fuel dongle and canister removal.

  15. Does what they're supposed to 4 Star Review

    Posted by on 17th Jul 2016

    Comes with copper compression washers but there is no stainless option for the 12mm.

  16. 1290 Adventure Intake System, SAS Emissions Removal Stage 2, Tuned Velocity Stack, Fueling Dongles 5 Star Review

    Posted by on 9th Nov 2015

    These products are first class and the fit, finish and performance are what you should expect from KTM ( but didn't get........)

    In my case for this motorcycle, I was not looking for more horsepower, I wanted to be certain that the air going into the engine was clean; and while I was doing that, decided to clean up the sometimes " lean condition". A side benefit was getting some space under the seat for storage.

    Very " neat and clean".
