Shaw ..A very reasonable question. The air intake / oiled filter upgrade seems to be the first 'mod' applied to just about any vehicle..except BMW .
When I got my 08 Z4 3.0si last year I just assumed I'd be stopping by the performance shop on the way home from the dealership.
When I searched for info I was surprised to discover that, unless I was tracking the car, there could be little improvement experienced over stock !
And here I was expecting to be warned about invalidating my warranty.
I took the advice and left well enough alone, taking comfort that BMW must do a pretty good job of engineering in the first place.
Plus ever since I was a kid and a slot car fanatic. I ruined my best car ..a Monogram Ferrari 250 GTB, by converting it into a 911 Porsche. The result was top heavy and performed like a turtle - rolling over at most corners ..
Well I am suspect at many mods because spending money for less performance just encourages the modifier to claim amazing results.
So be careful of any claims and you are wise to ask for advice here.
Cheers and good luck with your Dad's car. Just drive it and enjoy it. Save your money for tires !
