hi
actually i did a good search , until now i couldn't found any useful answer
my question is , which one should i get for my car , i want to switch from PRA k-pro to USDM PRB k-pro,i already bought 02-04 RSX-S k-pro , but which sensor should i run , the 02-05 Civic Si O2 sensor part#36531-PND-A11, or the one for the 02-05 RSX-S part#36531-PRB-A01 ?
