Let's face it, we weren't born with a wrench in our hands. While some of us have a good understanding of automotive mechanics, sound systems, and other car-related topics, we didn't always know as much as we do.
There was a time in my life when I didn't know what a header was, and I couldn't point out the intake manifold or throttle body in an engine bay, and I was too embarrassed to admit to it.
Well, I'd like to create this thread to give people the opportunity to ask what they'd consider to be "stupid" questions without being judged or laughed at, and give others the opportunity to answer them. Sure, you can google these topics for more information, but sometimes it's easier to have someone answer them for you and give a thorough explanation. No question is too stupid, mundane, or elementary.
The more knowledge people have, the more they can share it with others, so have at it. Does anyone here have any "dumb" questions they've been wondering about?
P.S. I have no idea how many people will actually post. This thread is a bit of an experiment...
