Just bought a replacement catalytic converter for my 2007 M35 after getting code P0430. Does anyone recommend using OEM over aftermarket, I'm looking into getting them from Z1 motorsports for around $200 per and my local infiniti dealer quoted me $400 per.
I also get the Bosch plug'n'play ones (with the OE connector) and has never failed me yet.
Do you happen to have the part number or a source for said O2 sensors? or are the ones on Z1 motorsports manufactured by Bosch? Thanks for your help on all my previous posts as well.
