im far from a gearhead so i need some direction...
im aware of the sprintbooster and the RPI intake, gonna add them within the next month but i would like some easy mods that wont cancel my warranty but will give a some more HP (by the way will i have a problem getting work done at a BMW dealer if i add a sprintbooster and/or RPI intake?).....any suggestions or will the sprintbooster and ram air sytem give some needed performance upgrade for my 530i?
keep in mind im not lookin to overhaul the engine or take it to the track and set some records in the quarter mile....just lookin for a boost thats cost effective. thanx

I'm curious about the rpi scoop too! if there's going to be a problem bringing it to the dealer. Dinan has the throttle body available for your car and won't void warranty I think.

Remove your charcoal filter and let your engine breathe, i felt a noticeable difference in exhaust and a tad bit in acceleration, felt more alive.
Maybe its cause i have the low horspower 05 model

How about a K&N filter to increase the airflow a bit? (minor bump in performance...bigger boost in smoothness)
