Thruxton, Scrambler & Bonneville Exhaust Headers O2 Sensor Block Off Plugs.

If you’ve already tuned the ECU on your Modern Classic, you might as well pull your O2 sensors too. Rather than leaving those expensive 02 sensor in the bike to have them destroyed by carbon build up, we have developed a low profile stainless steel block off screw that installs in seconds.

The screw allows the 02 sensor to be removed and the hole to be plugged, which makes wrapping your pipes a simple and smooth process. Each block off screw includes a copper crush washer, to ensure a proper seal and the low profile de-sign of our block off screw virtually disappears when installed into the headers.

Kit Includes:

• 2 - Raw stainless block off screws
• 2 - Copper crush washer.
