Noob -I recently bought a 2007 s locally from a non mini dealership. I see that there is an aftermarket cold air intake and filter installed. K&N typhoon. Is this good, bad? Should the factory air filter be re-installed? Cant seem to locate a dealer for these filters. I am in Northern BC and the closest dealership is Kelowna - 1000Kms away. A second question is my computer. I am getting a headlight displayed for 30 second or so then it goes away. Should I be concerned. i checked all the lights and they all appear to be working. Thanks in advance for your input.
