So when i got my setup a while ago, the Hooker Pro comp headers and the MAC X pipe it made room for me to run 4 O2 sensors like on a stock car. But two of my02 sensors were burned out and needed to be replaced. With the tuner i didn't need to have the rear 02 sensors becuase, as you all know, you can just turn them off. The only thing the rears are for is to tell you if your cats are good or not. . . but i digress. Anyways there are two taps in the Long tubes for your primaries and two taps in the X pipe for the secondaries so i bought new 02 sensors for the fronts but didnt want to put new 02 sensors in the rears becuase it would be a pointless waste of money. (By the way the old ones on my stock X pipe were seized in and i couldn't get them out with anything. . . .) So upon reaserch i found out that a spark plug from a 289 Ford V-8 has the exact same thread pattern as our 02 sensors. So $2 on some cheepo spark plugs and problem solved. So the moral of the story is if you need to fill your rear 02 holes just buy some cheapo 289 spark plugs instead of pointless new 02 sensors. And i guess you could hook up the spark plugs and make a flame thrower system

very nice, wish i would have thought of that... that thread pattern was a pia for some reason to find. Had to make plugs

They are hard to find because the threads are NPT (national pipe thread). An oil pan drain plug should also work if you don't want a spark plug sticking into your exhaust or any type of NPT plug should work

wow, I thought o2 sensors threads were bigger then that. I got plenty of 289 parts laying around,

you definately need to hook those up and make some flame throwers out of them!!

lol yeah but it would just shoot flames and burn out my mufflers lol

why not just leave the sensors in??? even if you are not using them

Becuase, like i said i didnt have the rears
