4 Packs O2 sensor extender spacer extension adapter.
These are needed when using a hho system or a test pipe. They are also used to lean out your vehicle for better gas mileage.
The extender has a 7/8 hex head which is the same size as most o2 sensors and it makes them easier to install not like the straight sided extenders.
