Z4 2.5 convertible 2008 what spark plugs

[TJC46]

As per the title. Just done an oil and filter change on my sons car.

Also done the air filter, so next time he comes home i was thinking of changing the plugs.

Car has done 46000 miles. About the right time to change plugs?

Which are the correct / best plugs to use ?

Yes, well worth a plug charge at that mileage. The older engines (M54) had a plug interval of 60k miles. I think the Z4 in question has the N52 which needs plugs more frequently, I think 40k miles is about right.

I'd say so. They look to be platinum/Iridium plugs in those.

On our 3 series with the same engine, the onboard computer tells you when to change them - we've done one set in 90k miles. From memory, they were a lot more expensive than the plugs on my old E46...
