My 98 spec B18cR motor swap has only 1 oxygen sensor. I am considering running a o2 sensor extender that pulls you sensor of the way of exhaust flow. I know Tegiwa sells them. So I'm sure some you guys are, or have ran them before. My question is, Are they safe to use, and do the help with flow at all? I've heard Subaru guys use them but I've heard they can lean out your fuel map. Any information would be great. Thanks.
 
the O2 extender bosses are used to pull the sensor out and 'bodge' its readings on the second O2 sensor on 2 sensor cars when you decat. it will screw up your closed loop AFR.
