I have tried to search this up but I can't really find any results. My question now is I have a 98 Civic EX, and I just picked up a DC Sports 4-2-1 Header. The o2 sensor on the DC header goes down under the engine where it joined into the 1 part while stock header o2 sensor position is right by the A/C condenser. Before I uninstall my stock header to put on the DC header, what should I know about how to install the o2 sensor because the wire just doesn't seem long enough.

 

just got to extend the wires..

 

what do you mean

 

cut 4 inches before 02 harness.

install new wires that reach to the new location.
