[Idaho Red Rocket 3]

My Wife and I have been test driving many differant Boxsters in our search for the perfect up grade from our '98 beginner Base Boxster. Something we have noticed on a few test drives is a hot burning smell. It is very strong coming from the engine compartment and can be smelled much stronger if you put your nose close to either the right or left side intake/vent ports. Otherwise cars seem to perform normally. Any ideas what this is caused by ? Is this a common phenomenon ?

BTW: On this trip...153 new best.
