The consensus on this site appears to be that NTK OZA446-E47 is the correct replacement part for the Z32 factory o2 sensor. Why does the NTK web site list the part number as OZA446-E27? I spoke to the contact at NTK who checked his psper catalouge which listed the same part number. He compared the two part numbers (E27 v's E47) and said that they had different lead lengths and different connectors. Possibly some internat differences also. He advised that the catalouge is never wrong and I should buy the E27. Has anyone bought E27 only to find them to be incorrect? Is there a difference between the Aus and J Spec? (there was only one listing in the NTK catalouge) Thanks.
Re: She's good value Agreed! Products are good value too :thumbsup: OZA446-47 is correct part number.
Not sure which is which but OZA-446-47 works perfectly btw the Nissan replacement O2 sensors are about $250 ea I believe. Some years ago one of the forum members (from the ACT I believe) identified that the above NTK part should be fully compatible. He installed these and ran the car for 6 months before posting.:thumbsup: Cheers, Peter
Hi Quinny, Its confusing I know, I have spoken to my NGK rep regarding the catalogue as it is misleading. I have sold many, MANY of the NGK/NTK OZA446-47 02 sensors and not had any sent back. I actually ordered another case of them today :thumbsup:.
