I just recently bought a set of new pipes and when i removed the o2 senor from my stock heads the rear sensors threads were chewed up and i was wondering if the 27683-07 was the correct part # to order a back-up just incase that it would thread in real easy and not take a chance of messing up the threads on the new pipes.

 

Yes that is the O2 sensor number.

 

Hey thanks

 

That is the right number for medium length. You can also get a longer one 27683-06 and a shorter one 27719-07. Remember to use copper anti seize (o2 sensor safe).

 

thanks

 

The 27719-07 (shorted) is used on the front. If you use the rear one you will have a lot of wire to cable tie down and hide. I changed my header pipe. I just bought new O2 sensors and left the original ones in the original pipe. This way if I need to put the original pipe back on, it is just a "Bolt Up and plug In set up. No need to worry about the sensors breaking.

 

Great idea ultra89rider.
