Frequently Asked Questions

What are these plugs used for?

They seal off unused oxygen sensor ports when you remove an O2 sensor, preventing exhaust leaks and unburned fumes.

Will these fit my Harley exhaust?

Yes, if your bike has a standard 18mm O2 sensor hole. Check your sensor port size before ordering.

Do the copper washers prevent exhaust leaks?

Yes — the sealing washers compress when the plug is torqued down to create a tight seal against the exhaust pipe.

How many plugs are in a pack?

Two plugs per pack — enough to cover both ports on a typical V-twin oxygen sensor location, or one bike with dual sensor ports.
