Frequently Asked Questions

What do these plugs do?

They seal unused oxygen sensor ports on the exhaust to prevent exhaust gas leaks and air intake at those locations.

How many plugs come in a kit?

Two plugs — enough for one typically unused sensor location on most Harley exhaust systems.

Do I need special tools to install these?

You need an Allen wrench to tighten the recessed head. Installation is straightforward — remove the old sensor and thread in the plug with the copper washer.

Will these fit any Harley with O2 sensor ports?

These fit standard 12mm x 1.25 threaded sensor ports on Harley-Davidson models. Verify your bike's sensor thread size before ordering.
