Piston Slap: Truncated Thoughts on Trunk Vents

Sebastian writes:

Every time I see a car on the street without its rear bumper, I see these vents under where the bumper is supposed to go. I have an Oldsmobile Cutlass Supreme 1993 that also has these vents inside the rear doors.

What is the function of those vents?

ShitHead It kicked on one time for me when a car abruptly turned into my lane. Worked as advertised. I was already about to lean into the brake as I was into the horn.
Theflyersfan I look at that front and I have to believe that BMW and Genesis designers look at that and go "wow...that's a little much." Rest of the car looks really good - they nailed the evolution of the previous design quite well. They didn't have to reinvent the wheel - when people want a Mustang, I don't think they are going to cross-shop because they know what they want.
Theflyersfan Winters go on around Halloween and Summers go on in late March or early April. However, there were some very cold mornings right after the summers went on that had me skidding a bit due to no grip! I do enough (ahem) spirited driving on empty hilly/mountain roads to justify a set of sticky rubber, and winters are a must as while there isn't much snow where I am (three dustings of snow this entire winter), I head to areas that get a bit more snow and winter tires turns that light, RWD car into a snow beast!
SCE to AUX My B5.5 was terrible, but maybe the bugs have been worked out of this one.
Zerofoo 5-valve 1.8T - and OK engine if you aren't in a hurry. These turbocharged engines had lots of lag - and the automatic transmission didn't help.Count on putting a timing belt on this immediately. The timing belt service interval, officially, was 100,000 miles and many didn't make it to that.
