Frequently Asked Questions
What size wrench do I need to install these?
The plugs use a recessed Allen-head design — you'll need a 5mm or 6mm Allen wrench depending on the specific port.
Will these seal properly without leaks?
Yes — the copper sealing washers are engineered to create a gas-tight seal when torqued to spec on the threaded ports.
How many plugs come in a kit?
Two plugs with copper washers — enough for one bike with two unused O2 sensor locations.
Do I need a gasket or sealant with these?
No additional sealant needed. The copper washers provide the seal; just torque firmly to spec.
