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.
Fits all standard size sensors with a 1/2 inch diameter tip.
The size of the extenders is M18 X 1.50.
Easy to install by unscrewing your O2 Sensor from your exhaust then screw your sensor into the extender, and then screw the two pieces back into your exhaust.
Threads made with dedicated tool, perfect precision and repeatability.
Made of high quality steel, high strength and durability.
