I have a 1994 4 door Integra with a LSV Swap, B18B1 block with B16A2 head. Bout to install a Narrow Replica and was wondering if the stock O2 sensor wire is long enough to fit the bung? Done a lot of research on here and google and mostly the Civics had to extend the wires. Just don't wanna run into the issue during the install. Already have a slimfan installed, just curious about the sensor, thanks!!

 

I have that header for my ITR. The integra O2 wire is too short. I had an O2 bung put in to as close to the stock location as I could eyeball. Unfortunately, the sensor rubbed against the T bracket.

When the sensor went out, I bought one for a 98 civic EX from sparkplugs.com. For whatever reason, the direct fit NGK and Denso sensors for the 98 EX were always WAY cheaper and I remembered them to have a longer wire. Turns out the wire is the perfect length to fit that header. Double bonus.

The sensor part # is the same as any other OBD1/2 integra sensor. The wiring is longer. That's the only difference. I think I got my direct fit Denso sensor for like $45ish.

 

Had to extent mine a couple inches on my coupe. Also the slim fan is probably less then half an inch from the header so make sure it's pretty snug to the radiator to get as much room as possible.

 

Thanks for the replies. It came with a 4 adjustable test pipe as well that has an extra O2 bung where the collector would normally bolt up to the cat. Hope that makes it fit instead of going for the one on the side
