We just bought a 2009 Mini cooper S hatchback. Fun as hell to drive just thought I would ask whats the easiest "drop in" mods a guy can do to boost the HP a bit?

Thanks

 

From the jump, I would go with this intake.

69-2004TTK - K&N 69 Series Typhoon Kits, Performance Intake Kit

I've had my Mini for almost a full month now and I purchased this intake a week after I bought the car.

I have a 2010 Cooper S and I'm in love with it. The intake took me about 30-45 minutes to install, give or take a few breaks to explain to my roommate how turbos work and sipping on a beer.

It didn't give me any trouble and I've immediately noticed a much deeper note and the BOV is much louder under any type of acceleration. I don't notice too much power from stop, but I can tell at highway speeds that I accelerates a little faster.
