When I was looking for mine, I looked at a lot of cars 25% N52, 75% M54. All the N52 engines sounded really tappety at idle, they may well have been fine and lasted forever, but I just didn't like the sound, so I deliberately went for a M54 in the end (80% of them sounded smooth).
Which would you pick? N52 (silver engine cover) or N52k (black engine cover)

Nope, all coupes came with the n52 engine unless you’re looking at the 3.2l M version. None came with the m54.
The black/silver plastic engine cover means nothing, I think it’s what they had in the spares store at the time

is it Rob? I was always of the assumption that 06-07 cars were silver then late 07-09 cars were black :?

If we’re talking the plastic clip on cover, I’ve seen posts on here from all years with both colours? :?
I think there was a survey once :lol:

Silver engine covers are for 06-07 cars, black engine covers came in from 57 onwards.

I think we’re talking about different things? I’m referring to the plastic cover that’s sits on top, they were black or silver randomly apparently :?
Are you talking about the actual valve cover which sits underneath?

OP's problem sorted then - N52!
I think it suits the Z4 better than an M54 with the way it revs, but accept that things generally seem to cost more to fix when they go wrong (like water pump & thermostat for example).
FWIW my current Coupe was built in August 2006 and has the silver top, my previous one was built in October 2006 and had the black cover, as well as the 3mm input jack for the stereo in the bottom of the dash. Luckily someone has retro-fitted one in the glovebox on my current car!

They’ve all got 6cylinders though haven’t they Rob?..... unlike a lot of more modern Z4sSmartbear said:Nope, all coupes came with the n52 engine unless you’re looking at the 3.2l M version. None came with the m54.
