Hi,

I have a 95 Accord LX that has a 95 EX VTEC engine swap (the VTEC isn't hooked up).

I'm trying to buy an NGK O2 sensor, but I'm unsure which engine I buy one for.


Here is the chart for the LX




And here is the chart for the EX


Sorry about the big image size, my bad.
Thanks for any and all help.

 

The LX has a 4-into-1 exhaust manifold, and the O2 sensor is located in the manifold.

The EX has a 4-into-2 manifold, then a 2-into-1 pipe under the oil pan, and the O2 sensor is located underneath just upstream of the catalytic converter.

I suspect the difference is the wiring pigtail on the sensor, and that depends on whether you took the whole exhaust system from the EX.

 

Thanks a lot! It looks like he did not change the exhaust system, so I'll go with the one for the LX. I sincerely appreciate the help as I was about to order both and send back the one that didn't fit.
Cheers.
