Hello.

New to the forums, and currently new owner of the 2008 BMW 528i, with 65K miles.
Couldn't find FAQ for performance modding.

Any owners here? or maybe anyone can tell me what performance mods I can do for this car?


Please dont write answers like: sell this, and buy bigger engine )))
Cause i guess the it's pretty the same engine as 530i, so there got to be the way to squeeze some more power from my 528 without turbo or supercharge mods.

 

There is but not much. The N52 engine was never meant to be powerful. Only things you can do is an aFe or KN air filter, air intake scoop, maybe an exhaust and a sprint booster.

 

in terms of performance, we have the RPI ram air kit and RPI exhaust available for your model =)
