I personally feel XP95 makes significant difference in engine response. I wish to upgrade mine to the G29, kindly do post more updates about your daily drives. Happy Motoring.

Thanks. I am really enjoying Z4, it’s growing on me as an everyday car. I want to put maximum miles on it. It is not as comfortable as 6 series but still reasonable as an everyday car. Upgrade to G29 and you will not be disappointed. Cheers.

It is E25 indeed. And I also got clarification from BMW India that B58 engine is E25 compatible
