BRITISH CUSTOMS O2 SENSOR BLOCK OFF SCREW
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 ($162 ea) in the bike to have them destroyed by carbon build up, British Customs has devel-oped 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.
