N55 Spark Plug Chang Internal
 

Does anyone know the recommended spark plug change interval for the N55 engine (3.0TT)? Have tried researching on the old inter-web but am getting 100k and somewhere around 50k for results.

Curious as I am at 47k now and was wondering if this should be/would be something the dealer will do under the 50k maintenance program.

I think 100k miles is the published interval for all BMW engines. "Service Info" on iDrive will tell you the interval and BMW maintenance plan will not change until requested by car.

Actually 100k is the interval for NA cars.

As an FYI for future reference the TT engines require a change at 60k, at least in the X5's. Took mine in today as it was due for front brakes and the SA ran the key, gave a spark plug due at 60k.

Yop, every 60k
