Same N54 engine in the 135, 335/335is, 535, Z4is + 1M. The tune (and the various hardware components on the 335is + 1M) are the only differences between them.

An additional radiator has been added behind the left-side front air intake, along with a more powerful electric cooling fan. An oil cooler is fitted opposite the second radiator, on the right side.
