Ok I own a 92 VX and just bought a d15b, havn't put the engine in yet but I thought I might gain a little power from my d15z1 and put my d15b exhaust mani on in my VX. the 5-wire VX o2 sensor came out of the vx manifold easy but the 1 wire d15b sensor won't come out of the my new manifold. is there a tool that I need to do this? I used an ajustable wrench on the VX sensor but it won't budge the d15b sensor I'm afraid of stripping it.

 

yes! there is a tool called o2 sensor socket. they sell it at an auto part store. remember to spray some wd40 first then go pick up the socket.

 

i had the same problem. use pipe wrench but be very careful.

 

Agreed
