Hey guys, I recently got myself into an z4 35is and was wondering if anybody could provide some information.

From what I've read about the n54, these motors apparently come out the factory with less than optimal cooling performance and I was wondering if it was possible to swap in all the additional cooling parts that the 335is gets over a standard n54 into a z4 35is. I would like to get a front mounted intercooler to assist with throttle response and keeping the intake air temps. as close to optimal as possible, but after consulting with my service adviser that would void my warranty.

Any input or thoughts about this decision? The one thing I really enjoy about my naturally aspirated 328 is how consistent and smooth the power delivery is. I knew every second of every day I drove it; how much performance the motor was going to deliver with how ever much throttle input I give it. No matter how many times I would take the car to redline it would perform exactly the same over run after run after run. The z4, although straight line performance is substantially greater than that of the 328, feels like its performance is noticeable effected by factors such as weather conditions, how long its been since I've done a pull, engine temp., and etc.
