Hi guys I have a 2015 535i msport. I've had it for about 2 months and I think I want to start slowly modifying the car for speed now. Suspension upgrades will be very soon as well.

I've done my research on many parts and tuning options but I'd like to get first hand recommendations on where I should begin. I'll be staying stock turbo so keep that in mind. Can anyone recommend a particular list or order of parts I should start with?

For example maybe
1. spark plug upgrade?
2. intake?
etc...

I have 550 and my first upgrade was Pedal commander and Race Chip. You will feel a big difference.

Spark plugs don't add any power unless they were well past their service life. They become a supporting mod at much higher boost levels, but not something you're likely do need to deal with.

Intake make some noise, does little else.

Get a proper flash tune if you want added performance. Consider upgrading your charge pipe at the same time as they are prone to rupturing under increased boost pressure. I highly recommend a tuner that is intimately familiar with the F10 chassis like MissionPerformance.

okay well thats a start, kinda.

Charge pipe, Intercooler, Downpipe, Tune is best starting point to get some more power. Never any performance mod if maintenance isn't current.
